*more Killervibe coming after this chapter. More to come

"What am I doing?" Cisco's voice was weak, but he sounded like himself again.

He reached out for Caitlin's arms and tried to leverage himself up. She realized what he was doing and stood, taking half his weight from him. But still, she hesitated.

"Where are you going?!"

He nodded over toward the shimmering breach in the living room.

"I gotta go back... fix what I... uh..." he gave as much a smirk as he could manage, "fixed."

Caitlin followed him toward the breach, "Cisco, wait, you're-!"

He disappeared into the portal and she stared into the dimensional rip. She felt the warning she didn't want to believe slip out of her mouth,

"You're dying."

Cisco opened up breach after breach. Reversing things he'd done in his weird power trip so that the timeline would realign the way it was... to the best of his ability.

He felt terrible. And each breach he opened or closed he was afraid he might collapse. Start seizing. But he needed to fix what he'd broken. Even if that meant taking Dante from him again.

He stopped himself from protecting Reverb.

From protecting Rupture.

From stopping Barry on the night he created Flashpoint.

With every timeline repair, he felt less like his head was being crushed. And a brilliant, blue burst of light exploded around his closing breaches. Knowing now, that the blue lights that had been spotted all over Central City over the past month had been caused by him, was a little anticlimactic, to say the least.

But it was also chilling to know that he could not only see every possible timeline, but he could change them. And it was so easy. He wondered vaguely if his actions would have the same consequences Barry's did. Or if it was possible that going back to stop yourself from altering the timeline was actually returning the timeline to its original state.

The thought of this was too painful to linger on and Cisco already felt like he might throw up blood and pass out, so he filed that theory away for now.

But he was definitely exhausted. Maybe not dying, but drained. He counted off all the timelines he'd altered and had to repair in his head. That had to be all of them, right? He'd be dying if there was anything left...

He burst through the last breach, back inside his apartment, and closed it. He made a step towards Caitlin, and collapsed.

Caitlin was on her knees, holding Cisco's upper body close to her. He wasn't conscious, but he had a pulse. He was breathing. Hell, he even looked relaxed for the first time in months.

Caitlin gently stood herself up and attempted to lift Cisco with her. But he was deadweight in her arms.

Not wanting to risk waking Cisco, who was finally getting the kind of peaceful rest he needed, Caitlin texted Barry:

Cisco's passed out in his apartment, he's okay but, help me get him to his bed?

It only took a minute or so and Caitlin heard the unmistakable whoosh of Barry arriving outside Cisco's door. Caitlin slowly settled Cisco onto the floor and got up to let Barry in.

He gave her a slight nod and headed toward Cisco immediately. He crouched down next to him and lifted him up.

Caitlin pulled the comforter over Cisco as Barry settled him into his bed. Barry gave Caitlin a little smile and went to wait for her in the kitchen. Turning back to Cisco, Caitlin smiled at him. She kissed his forehead lightly and headed to the kitchen.

"Do you think he's gonna be okay?" Barry whispered, as Caitlin leaned against the fridge.

"Yeah, he's... he'll be fine."

Barry glanced back toward Cisco's bedroom and continued,

"Do you think he'll ever forgive me?"

Caitlin sighed heavily through her nose.

"I don't know, but it's hard for someone to get over something like that when the person who might be responsible isn't being responsible for it."

"But I might not be!" Barry was still whispering but as his voice raised at the end, he quickly quieted himself, "I didn't mean for anything to happen to Dante...

"That doesn't change the fact that something did happen. And whether you caused it or not, it happened, and Cisco's hurting." Caitlin eyed Barry doubtfully and said, "Have you asked him how he's doing? Or tried to see what he's going through at least?"

Barry opened his mouth to respond and closed it again. He ran a nervous hand through his hair and muttered,

"There's nothing I can really do to fix this, is there?"

"You can be there for him. That's all you can really do."

Caitlin monitored Cisco from the chair in the corner of his room for a while. She checked his temperature, pulse, and breathing pattern, and then went to go wait in his living room. Lingering in the doorway, she whispered,

"You're gonna be okay, Cisco. I promise."
