[Protostar bridge]

DAL How's our engine holding up with the new Protostar?
HOLO-JANEWAY: Plasma injectors at maximum efficiency. All systems humming just like new.
MAJ'EL: And you are sure the ship is able to sustain this speed?
POG: Ha, ha! Sustain? Speed is what this baby is built for.
ZERO: Nothing to fear. The protowarp is merely bending Space-Time around us, making our considerable journey go by in a flash.
GWYN: We're approaching Voyager at zero mark three five.
DAL: Take us out of protowarp, Zee.
(Gwyn's stabiliser stutters.)
DAL: You okay?
GWYN: Just been a while since I did that.
ZERO: Voyager. So glad to see her again with new eyes.
CHAKOTAY: She's a whole lot different than the one I remember.
(Clean-shaven and in uniform.)
DAL: Oh, looks like someone's ready to be sent to the admiral's ready room.
GWYN: Great. You look great.
CHAKOTAY: Do I look like I'm trying too hard?
HOLO-JANEWAY: Is that a bad thing?
CHAKOTAY: I only wish I would have come back sooner. I'd have fewer grey hairs.
HOLO-JANEWAY: New use dwelling on what could have been.
ZERO: We're approved to beam aboard.
POG: Ha, ha, yeah.
ROK: Janeway, I know you're not technically a pet sitter, but...
HOLO-JANEWAY: I'd be happy to watch over Bribble, even if I am more of a dog person.
(Creates a laser light for Bribble to chase like a cat.)
HOLO-JANEWAY: I believe this will entertain me more than it will you.

[Transporter room]

EMH: Oh, my stars. My young protegees. But you were gone. How? Captain Chakotay. I never thought I'd... that you...
CHAKOTAY: That makes two of us, Doctor.
EMH: The Admiral will be very pleased to see you.
CHAKOTAY: Not more than I will be to see her.
EMH: Her?
CHAKOTAY: Admiral Jellico?
JELLICO: Chakotay? How is this possible?
DAL: Hold on. Where's Janeway?
JELLICO: Admiral Janeway gave her life trying to rescue Captain Chakotay from the wormhole. She perished in the Infinity along with Commander Tysess and Counsellor Noum.
EMH: Not one of you remembers?

[Corridor]

EMH: We need to get you to sickbay for further analysis.
CHAKOTAY: I don't understand. You're telling me Kathryn is gone?
ROK: But that isn't what happened.
DAK: We took the Infinity, not Janeway.
EMH: The fact that you all remember the same incorrect reality suggests you may be experiencing a shared psychosis, unless... Did you pass through any tachyon storms or cosmic anomalies?
MAJ'EL: These logs confirm Janeway did perish on the Infinity. So either we are experiencing shared psychosis or we are on the wrong Voyager.
EMH: Let's pretend for a moment that what you say is true. That would mean you're from an alternate reality. One where Admiral Janeway is still alive. If that's true, then well, it's my duty to reunite a crew with their captain.
ROK: You believe us?
EMH: Believe? Maybe. Can I help in an emergency? That's my job. But first, meet me in sickbay. I need to rule out all other explanations.
CHAKOTAY: I trust the doctor. We'll get to the bottom of this.
ZERO: We'll take another and meet you there.
ROK: See you in Sickbay.

[Turbolift]

DAL: What's wrong?
GWYN: It's like a wave came over me.
(Controls glitch. Doors open.)

[Corridor]

(Dark, debris.)
POG: Oh, they really let this deck go. Jankom approves.
DAL: Hey, Doc, you in here?
(Chakotay forces the doors.)

[Sickbay]

GWYN: Is anyone in here?
OKONA: Back off! I found it first!
DAL: Okona?
OKONA: Hey, I know you guys.
MAJ'EL: You are familiar with this dishevelled man?
GWYN: He ditched us on Noble Isle.
OKONA: Ditched? I left to get you guys help. But had I known how dangerous you all were, I'd have split earlier. Hey, where's the big rock girl? I liked her.
GWYN: Rok, Zero, where are you?

[Another corridor]

(Everyone is in green uniforms.)
SOOL'U: Someone alert Captain Tuvix.
ZERO: Oh dear. Perhaps we took the wrong turbolift.

[Sickbay]

CHAKOTAY: Chakotay to Rok and Zero. Janeway, do you read me?
MAJ'EL: I suspect you will not reach them because we may have unknowingly stepped into a new reality.
DAL: Back up. What did you mean, how dangerous we all really were?
OKONA: The secret weapon on your ship? That thing infected every Starfleet vessel in the quadrant. I'm amazed you guys made it out alive. Ah, don't play dumb with me. You guys tore the whole Federation apart.
CHAKOTAY: Admiral Janeway, did she come through here?
OKONA: Sorry, friend. You're the only Starfleet officer I've come across. This ship was left for scrap.

[Mess hall]

GWYN: If Rok and Zero took the other turbolift, they should be here by now.
POG: Unless it sent them to some other crazy parallel universe.
MAJ'EL: Rok and Zero are intelligent and capable, and given we are in no immediate danger, we need not assume they are in harm's way.
DAL: No harm? We are stuck in an alternate reality with this guy.
OKONA: Hey, hey, let me take your temp. I love your vintage Starfleet uniforms. We can get a pretty sweet price for that on the black market if we just er...
ALL: No!
OKONA: I'm just throwing it out there.
CHAKOTAY: I've been through something like this before. Somehow we're moving through different realities. If we can find a way back to our own, we should be able to reunite everyone.
POG: What do you mean should?
CHAKOTAY: We can't fix anything until we understand how this happened.
(Murf points to the windows. Protostar is frozen.)
POG: Er... how do we fix that?
GWYN: Remember how Wesley said the paradox created by the Protostar being lost in time weakened the fabric of the universe? Well, I think when we protowarped, we punched a hole right through that fabric.
MAJ'EL: And now, that interphasic rift is splintering through this ship.
POG: Oh, great! So all our past mistakes are coming back to haunt us.
GWYN: Not mistakes. Different choices.
CHAKOTAY: You two could be on to something. From the Protostar, we beamed aboard deck nine to a reality where Janeway went through the wormhole.
DAL: Then we took the turbolift up to sickbay on deck eight to a reality where we didn't stop the Protostar from destroying the Federation. Two realities, both connected to what we did and didn't do.
CHAKOTAY: If we follow that pattern, every deck could be a new reality.
POG: Why is this only happening to us?
CHAKOTAY: We created the anomaly. It must be tied to our quantum signatures.
MAJ'EL: Perhaps we can use the deflector dish. Create a broad spectrum warp field with an inverse tachyon pulse and...
CHAKOTAY: Yes! That would seal the rift and untangle this mess we're in.
DAL: I don't know what you're saying, but I like the way you're saying it.
CHAKOTAY: Fix the rift and we all bounce back to our universe. We just need to get to the bridge and the deflector dish to do it.
DAL: Oh, please tell me Vulcans just have a hard time being happy.
MAJ'EL: The bridge is eight decks above us.
POG: Oof. That's a lot of realities.
MAJ'EL: Too many for Gwyn to survive. I saw the coordinates change on her armband in the turbolift.
GWYN: She's right. They're different.
POG: Her armband was built to keep her in one reality, not dozens.
DAL: So that's why she felt faint.
MAJ'EL: And will continue to grow fainter.
GWYN: I can handle eight levels.
DAL: If Zero and Rok are okay, maybe you can stay here and...
GWYN: You might need me. I said I can handle it. We stick together.
POG: Or we could take a shortcut and just have Captain Ponytail over there beam us to the top.
OKONA: Huh? What?

[Okona's ship]

CHAKOTAY: Thanks for indulging us.
OKONA: Yeah, I still don't totally get this reality hopping, but I hope you find what you're looking for. Uh-oh. Hold on. There it goes. I sold a few parts to the Andorians. It should still work.
POG: Whoa, whoa, whoa! Should?
OKONA: Good luck. Wherever you're going.

[Transporter room]

(Gwyn is dizzy.)
GWYN: I'm okay.
DAL: And everyone else?
POG: Hey! Maj'el got left behind.
CHAKOTAY: And this isn't the bridge.
POG: Should work. Should have said, doesn't work.
(A leather-clad figure enters.)
CHAKOTAY: Kathryn?
M-JANEWAY: Chakotay.
(Armed guards, and a person with a goatee...)
M-CHAKOTAY: Pinch me. I'm seeing double.
DAL: When did you get a twin?
POG: With whiskers.
GWYN: What nightmare are we in now?
CHAKOTAY: The mirror universe.

[Brig]

CHAKOTAY: This is the last dimension I wanted to visit.
POG: You know this place?
CHAKOTAY: Starfleet's had run-ins with the mirror universe before, but it's always bad news.
GWYN: Mirror, like a reflection?
DAL: An opposite reflection. What's this place have to do with the Protostar?
CHAKOTAY: We can figure that out once we escape. This dark universe is dangerous. Humanity is bent on galactic conquest instead of exploration. And the locals are anything but friendly.
M-JANEWAY: I'd listen to your dashing captain. You slithered right into the viper's nest.
M-CHAKOTAY: Starfleet. I thought we installed new safeguards to prevent travel between our universes.
M-JANEWAY: If mere children found a way here, that's a security breach for the new Terran Armada.
CHAKOTAY: You won't get anything out of us.
M-JANEWAY: Oh, won't I? I'm sure the agonizer will loosen their tongues.
(Mirror Chakotay activates a chamber.)
POG: Ha. Agonizer? Was Mean Machine taken?
M-JANEWAY: Enjoy. I know how you love your interrogations.
M-CHAKOTAY: Who to agonize first?
CHAKOTAY: Take me.
M-CHAKOTAY: So chivalrous. But no. I think I'll start with the cute one.
(Murf.)
M-CHAKOTAY: Everyone else, hands to the wall.
POG: Oh no, not the cute one.
(As soon as the forcefield is down, Murf attacks, and lays mirror Chakotay out cold.)
DAL: Nice work, security officer.
CHAKOTAY: Never trust the cute ones.
(One costume swap later.)
CHAKOTAY: Pose as my prisoners, and I'll get us to the bridge.
POG: What about the whiskers? Hey, hands off, Jankom Pog's thorium grease.
DAL: Huh. And now you're evil.
(Murf mimics the goatee.)
GWYN: Not exactly needed, Murf, but I like the enthusiasm.

[Corridor]

SOLDIER: Commander.
CHAKOTAY: As you were, soldiers.
GWYN: That was too close.
DAL: So far, so good.
CHAKOTAY: Janeway.
M-JANEWAY: They don't look very interrogated to me.
CHAKOTAY: They were easy to break. I was escorting them to the bridge so they could show us how they got here.
M-JANEWAY: What is that? Some kind of spy device? Remove it, alien. Now!
GWYN: I can't. I'll die.
M-JANEWAY: Excuse me?
DAL: She said no.
M-JANEWAY: Ah, ah, ah. This is my ship. She takes it off, or you both take a trip out the airlock.
CHAKOTAY: I already examined the device. It's no threat. Trust me.
M-JANEWAY: Oh, I always trust my first officer. But he's not here.
CHAKOTAY: Run!
(They flee into a turbolift. Mirror Chakotay leads a squad to follow.)

[Cetacean Ops]

GWYN: Sorry, Chakotay. I know that wasn't the reunion you were hoping for.
DAL: I should have kept my mouth shut, but I couldn't just let her...
CHAKOTAY: Don't apologise. Some people are worth fighting for, no matter how many realities you fight through to get back to them.
DAL: Just a whale.
M-GILLIAN: Security, the intruders are here.
POG: Even the whales are evil?
M-GILLIAN: All hail the Terran Empire.
M-CHAKOTAY [OC]: Check in there!
M-CHAKOTAY: Sweep the perimeter. He's got my uniform. Come out, come out, wherever you are.
(They try to sneak out.)
M-JANEWAY: I always hated children. Move. Now.
POG: Drip, drip!
(His Mitt connects with a panel, trapping their captors.)
COMPUTER: Activating emergency forcefield.
M-CHAKOTAY: Stop them! Don't let them out of here alive!
M-JANEWAY: Override this forcefield or I'll have your head.

[Corridor]

CHAKOTAY: The bridge should be just ahead.
GWYN: Are we going to another reality?
CHAKOTAY: Thankfully, no. It's on this deck.

[Mirror bridge]

CHAKOTAY: The admiral is in danger! Anyone who doesn't protect her will face the Agonizer!
(The crew run out, the gang sneak in.)
CHAKOTAY: Computer, seal bridge doors. Do not open again without my command.
COMPUTER: Voice authorized. Affirmative.
CHAKOTAY: Recalibrating the deflector dish.
DAL: Oh, no.
CHAKOTAY: Is that...?
GWYN: The Loom. Wesley said he'd keep them away.
DAL: But that was in our reality. This is somewhere else.
CHAKOTAY: They are much worse than you described.
POG: So stop staring and do something!
CHAKOTAY: It's still recalibrating.
GWYN: I can remodulate the shields to match the Loom's phase variance.
DAL: You sure that'll stop them?
GWYN: Slow, not stop.
(The Loom land on the shields. The Mirrors blast a hole in the doors.)
M-CHAKOTAY: In there!
M-JANEWAY: Drop it, goo bag.
CHAKOTAY: If you do this, none of us survive.
M-JANEWAY: Why should I believe you?
CHAKOTAY: Because no matter what reality we're in, I could never hurt you.
M-JANEWAY: What are those things?
GWYN: The Loom. They hunt and erase any kind of paradox, like the one we're in now.
DAL: But if you let us fix that rift, they should go away. We go back to our reality, and we can pretend like none of us ever met.
M-JANEWAY: Should?
POG: Or we get eaten by time monsters.
GWYN: They're breaking through!
(Mirror Janeway fires ship's phasers at the Loom.)
M-JANEWAY: This doesn't mean we're friends.
CHAKOTAY: No, but I'll take what I can get.
(A Loom breaks in.)
CHAKOTAY: The deflector dish!
(Time slows. Gwyn is the only one who can move.)

[Voyager transporter room]

DAL: We did it.
ROK: Yes! We're back!
MAJ'EL: But how!
ZERO: And I was just growing used to Captain Tuvix's Vulcan-Talaxian fusion cuisine.
MAJ-EL: That was highly outrageous.
EMH: Oh, my stars! My young proteges! But you were gone! How? Captain Chakotay. I never thought I'd see you again.
CHAKOTAY: Good to see you, Doc.
JANEWAY: Chakotay?
CHAKOTAY: Is it really you?
JANEWAY: What's on your face?
CHAKOTAY: I've thought about this moment for what feels like an eternity. But now, it's like I never left.
JANEWAY: Because you're home.
POG: Yeah!
GWYN: I told you I could handle it.
DAL: It wasn't you I was worried about.
NOUM: You went to the mirror universe?
POG: You're not going to believe this. Even the whales were evil.
DAL: Whatever our reality throws at us, I'm glad I'm in this one. With you.
GWYN: Me too.
