The team was all gathered back at S.T.A.R. Labs. They had extracted the glass pane Y/N was stuck in and were examining it in the workshop. The stuck speedster paced in place with nowhere else to go.
Caitlin: Y/N, can you hear us?
Y/N: .delffum elttil a s'tI. adniK
They all looked at him in confusion, hearing his voice distorted.
Cisco: Uh, what?
Y/N: .delffum elttil a s'ti dias I.
Caitlin: Why does he sound like that?
Wells snapped his fingers upon figuring it out.
Wells: Mirrors reflect objects. They show them in reverse. Maybe that's what we're hearing. Cisco...
Cisco: Already on it.
Cisco walked over to his workbench. He pulled out a recorder and set it to reverse. Walking back over, he connected the device to the mirror.
Cisco: Try it now.
Y/N: Can you hear me? Can you understand what I'm saying?
Cisco and Wells clapped over their achievement.
Caitlin: Loud and clear, speedy.
Y/N: Alright. Can you guys get me out of here? I really need to pee.
Cisco: Have you tried phasing?
Y/N: Yes. It's not working.
They all stood there, thinking. Barry-1 suggested an idea.
Barry-1: When I was stuck in a mirror, I was able to phase out by freezing the mirror. The molecules within the mirror act as a wormhole and-
Wells: Are in a hyper state of flux. All we need is something really cold to slow them down.
They all looked over at Caitlin. Barry-1 looked over at them with a questioning look. Cait nodded and closed her eyes. She concentrated on very specific memories and feelings, ones she didn't always like but that she found to do the trick.
When she opened her eyes again, they glowed a brilliant white. Barry-1 jumped back when he saw her hair turn white. Caitlin's lips became blue, her skin a ghostly pale color. She almost immediately changed her body posture, slumping to the side like a model leaning on her hips.
Frost: What's all the trouble, boys?
Wells: We need you to freeze this mirror so Y/N can phase out.
Frost: Oh, of course. It's always business with you men.
She turned her head, giving a grin at Barry-1. The stunned man continued to look at her, not quite sure what to make of what was happening and especially the others' calm demeanor about it. Frost strutted over to the mirror and stopped. She looked at her own reflection in it past Y/N's body. She turned to get a better look at her backside.
Frost: I like what you've been doing lately, Caity. Have you been working out? It shows. Look at those calves and that-
Y/N: Frost.
Frost: What? I'm just admiring these cheeks. I'm glad Caity gave you a proper look at 'em. For a moment, I was afraid I'd have to do it myself.
Y/N: Frost!
Frost: Alright, alright. Chill, lightning freak. Ha! Chill. See what I did there? Watch out Cisco, I might steal your jokes, then all you'll have left is that brainiac sized noggin and surfer boy hairdo.
