"W...well of course I want to change back." The rabbit says, looking over his small, plump, furry form. "I have a girlfriend back at home. I can't imagine she'll still want to be with me when I'm like this..."
"Well, okay, what should we do then?" You ask, looking apprehensively around the room. The rabbit ponders for a moment before coming up with an idea. "So... there's two of us, right? How mirrors do you think are in here, at least 500?" You see row after row and wall after wall full of mirrors. You think you even see a stairway off in the corner. "Probably more than that." You say.
"Well, what I'm trying to say is that now that there's two of us, we can check all the mirrors in double the time! There has to be at least one somewhere that can change us back." He hops around a little exitedley before realizing it and settling back down sheepishly. "I can take that side of the room, you can take this one." He tries to point but his new qaudrupedal position prevents him from pointing with his paw.
You ponder it for a moment. "I mean, there are some risks. Either of us could change into something too small to see the mirrors. Or we could lose our minds in the new forms and forget we ever were human..." You look down at the rabbit sitting below you before turning to look into the tiger mirror again, admiring your feline beauty. "I mean, I'm pretty sure you don't want to be a rabbit forever, and I'm...not sure how I feel yet, but I can definitely try and help you change back."
"Great!" The rabbit says, wiggling his tail. "Uh...I'll take this side of the room, and you take that one."
The rabbit hops off towards the right while you saunter to the left, slightly sad at the prospect of losing your tiger form.
