Ronnie's POV
I jump a mile high when the phone rings. "Hello?"
Cisco's voice replies, sounding tense and worried. "How fast can you get to S.T.A.R. labs? We have a situation."
Caitlin! I hang up quickly and run to fond Professor Stein. "Professor!" I shout when I found his office empty.
"What's the emergency, Ronald?" he asks calmly, returning with a stack of papers.
"S.T.A.R. labs needs us, they have a 'situation'," I say. we merge and fly to the lab, but the sight that greets us is worse than anything we could have imagined.
Caitlin, my Cait, lay on the floor, her hair white and her eyes hungry and pale blue, and her skin. Oh God, her skin freezing to touch.
"Ronnie," mutters Prof Stein, looking faintly sick. Cisco was sat in the middle of a pile of wreckage, staring off into the distance.
"What happened?" I ask, looking round in horror.
Prof Stein kneels down and gently prods Cisco. The young engineer snaps to attention, breathing heavily. "What happened?" Stein asks gently.
"Dr Wells killed me!" Cisco sobs. "Wait, no. that didn't happen. The Accelerator 2.0 blew up. Caitlin and I are meta-humans." He turns to look at her. "She needs heat. That's why I called you."
Stein and I merge, and take Caitlin's hand. I feel a strange pulling sensation, as if she is taking something out of me. Slowly, she sits up and her hair and eyes return to their normal colour. She loses the hungry look and smiles at me. "Ronnie," she whispers. Joy rushes through me like adrenalin.
"It's me Cait," I say.
"Me too," adds Stein.
Caitlin laughs. Cisco smiles, but he still looks haunted. "We can't tell anybody. At least, not until we've defeated Eobard Thawne," he says, looking down.
"WHAT?" I shout. "Look at Cait, look at you. Actually, what happened to you?"
"This." Cisco lets out an inhuman cry and smashes what remained of furniture. "Also, I appear to be able to remember things that haven't happened."
"Possible alternate timelines," says Stein.
Caitlin shivers, and I set my hands on fire to be able to give her more warmth. She smiles gratefully. "Anyway," she says. "Barry will be on his way now. We'd better clean this place up."
Caitlin's POV
We cleared everything up surprisingly quickly, and before we knew it Barry was back.
"How's the Accelerator going?" he asks.
"It's ready to go," lies Cisco, pulling it off surprisingly well.
"Great. Any news on Eobard?" Barry asks Firestorm. They were still merged to give me enough heat to look human.
"Actually yes," replies Stein. "We traced his phone to a warehouse near CCPD, but there's no telling if his phone is actually with him."
Barry nods. "Caitlin, can you work on traffic cams and the blah nearby?"
"On it," I say, slowly letting go of Ronnie's hand and beginning to type. The cold gets worse immediately, and this time there is pain as well. I focus on the task in front of me, until I see the tips of my hair turning white, and instead decide to focus on looking myself. I think happy thoughts: Cisco making me laugh, Ronnie proposing to me, helping Barry take down bad guys. My hair returns to its normal colour, but I just can't do this anymore. Dr Caitlin Snow no longer exists. I am something else now, something else entirely.
"How's it going?" Cisco asks, coming over holding his tablet.
"Good," I whisper, not meeting his eyes.
"I can tell when you're not ok," he points out.
"Well, I doubt there's anything you can do about it," I snarl. He places a hand over mine and I flinch away instantly. "Don't touch me."
"Look, I'm finding this just as hard as you," he says.
"Somehow I doubt that." My hair starts turning white again, but I'm out of ideas. Right, traffic cams. I rewind the footage until I see Eobard Thawne. I still can't get used to the sight of him without the wheelchair and glasses.
Barry comes back holding his phone. "I just spoke to Joe, he says nobody at the CCPD has seen him, so maybe the phone was just a red herring."
"It's not," I say, pointing to the screen in front of me. "He was definitely there." Barry leans over me to get a closer look. I can feel the heat coming off him and have to restrain myself.
"Can you-" begins Barry but I stand up, cutting him off.
"I'm sorry," I announce. "I can't do this anymore." I let go, and I feel myself turning into the creature I was before. I leave the room and follow my instincts. Ignoring the stares I get on the street, I go to the warehouse. As I knew he would be, Eobard Thawne is there. I look him dead in the eye, ignoring the surprise and confusion.
"The name's Frost. Killer Frost."
