What if the paladins went wormhole jumping, but ended up in one of the alternate realities Slav talked about?
All of the Paladins: *currently on the alternate version of earth*
Keith: We need to get out of here. The longer we stay, the more problems our reality might be facing.
Lance: Yeah, but how? We wanted to go to another planet, but ended up in another REALITY?! How the heck did that happen??
Allura: Calm down, guys. We'll figure something out, I'm sure of it.
Pidge: Yeah! I'm sure after a little bit of science, I can-
Hunk: Uh.. guys?? Look! *points to 5 identical lions landing on the planet*
Keith: Our lions! This must be the alternate version of us.
Alternate Keith: *gets out of his lion and sees the normal paladins* Who are you?! Why do you have your own Voltron?!
Keith: Wait, let us explain-
Alt. Keith: *transforms his bayard into the sword* Explain then. And it better be good.
Alt. Pidge: *gets out of her lion and runs over to Keith* Love, put your sword away!
Pidge: *stares at her alternate self shocked* Hold on- WHAT?!
Alt. Keith: I don't trust them, babe. They could just be galra trying to imitate us.
Keith: *stares at them shocked as well* Wait a minute-
Alt. Pidge: If they were imposters, the lions would probably look more galra like. Let's hear their story first, okay? *holds Alt. Keith's arm gently and looks at the paladins apologetically* Sorry for my boyfriend; he can be a bit jumpy.
Pidge: Wait, I'm- I mean you're dating Keith?!
Alt. Pidge: Of course I am. No else I'd rather be with. *blushes a bit before looking confused* Are you not dating him too? *points to normal Keith*
Pidge and Keith: *blush hard and look at each other* Uh- we.. I- um!
Alt. Pidge & Alt. Keith: *look at each other unimpressed* They're from a different reality.
