"Are you sure you're feeling okay?" Barry asks, his brows arching in concern.

Caitlin nods, smiling reassuringly. "I'm sure Barry, the bracelet is doing wonders for keeping the cold at bay." The thought of turning into Killer Frost again is a terrifying one, she hasn't taken the bracelet off at all since she was given it.

Barry nods, not entirely convinced but unwilling to press the point. He looks at Cisco and asks. "How are Wally's tests looking?" His foster brother had woken up three weeks ago, with the speed force running through him and since then they'd been training together, they'd even stopped a few criminals together as well.

Caitlin replies first, a little hurt that Barry is asking Cisco first, silly she knows, but still. "Wally's vitals are fine, everything is running smoothly there, he's perfectly healthy." She sees Barry flash her an apologetic smile and she relaxes, and takes his hand.

Cisco watches all of this relieved, he'd been afraid something might change between his two friends after she had come out, but evidently not. "Wally's got a lot of speed in him. Whatever it was that was in that lightning strike, it's given him a lot of power. He's faster than you were at that stage."

Barry nods, he's noted that himself, Wally can do things with his speed, that Barry could never have dreamed of being able to do when he'd first gotten his power. "Yes, that he is. But he needs to focus a bit more. He's too used to running out on steam to impress someone or the other." Caitlin shoots him a smirk. "What?" he asks innocently.

Caitlin harrumphs. "If I remember correctly, when you got your speed you used to run off to talk to Iris, and impress her that way." She keeps her voice teasing, though there is a small flash of jealousy which she knows is unwarranted, Barry loves her, Caitlin, not Iris, she knows this. Yet the voice in her head, her voice, keeps reminding her otherwise, or tries to anyway.

Barry laughs slightly, bringing Caitlin's hand up to his lips and brushing a soft kiss to it. "True, but I quickly realised how stupid that was. Thanks to my physician."

Caitlin laughs. "I see."

Cisco clears his throat. "I've also done some research into Alchemy and this thing called the Brahmastra."

Barry quirks an eyebrow up in question. "What have you managed to find?"

"Well, bugger all on Alchemy, it's almost as if he appeared out of nowhere. As for the Brahmastra, well it appears to be an old thing, from prehistoric India. Made during the time when Europe was still cavemen and the like. An old weapon that could create and destroy life, and gave its wielder unlimited power. It is thought to have been part of an old tale from India, something called the Mahabharata."

"The story of good and bad?" Caitlin enquires, and at Cisco and Barry's questioning looks she blushes. "I did a bit of reading on the Mahabharata when I was younger."

Barry smiles. "What's the relevance of the thing to Alchemy?"

Cisco takes a moment to consider the question and then says. "I'm not sure, but I think I know what its relevance is to Savitar."

Barry raises an eyebrow. "Go on."

"Savitar is the Hindu God of Motion, in the stories it is claimed that he helped shape and make the Brahmastra, and that it gave him his power. From what I've learned, he might be the very first speedster, before him there were none. And it seems that the power he got drove him mad, he continued to hunger for more and more speed, he did experiments on himself that turned him into a monster, encased in armour, more beast than man. Eventually, he went mad, and the gods had to seal him away. Another speedster called Vega, sealed him away in the speed force, and took command of the Brahmastra, as a means of ensuring that Savitar could never make it out of his prison." Cisco says.

"What happened to Vega?" Barry asks.

"He was murdered. One of Savitar's followers killed him, and took the stone, but the stone ended up driving the man mad, and he killed himself. The stone is lost to history after that. Whether it ever really existed at all, is another question." Cisco replies.

"Do we know how Vega defeated Savitar?" Barry asks, the memories of the beating he took fighting the God of Speed echo in his mind.

Cisco shakes his head. "No, nothing I've read says anything about that. It's almost as if the records of it were lost to time as well."

Barry groans. "Great, so now there's going to be more encounters with the thing, and I'm going to have to struggle through it all again."

"Well, we'll be there with you, every step of the way." Caitlin says, reassuringly, hating the look of pain that flits across her boyfriend's face.

Barry smiles in recognition of this. "Yeah, that's true. Just got to take it one step at a time I guess." At that a thought runs through his head. "Do you think you might be able to run a voice recognition on Alchemy, see if any hits come back?"

"You think he might be an actual person?" Cisco asks.

"I think so, something about him seemed familiar." Barry replies.

Cisco nods. "I'll see what I can do."

Barry nods and then leading Caitlin out of the cortex, he whispers. "Have you thought about what I said this morning?"

Caitlin sighs. "I have, but I'm not sure if going to see my mother would do any good. This thing is beyond her."

"How do you know?" Barry asks curiously.

"Because I asked her about certain similar conditions before, and she said there was no cure." Caitlin replies dejectedly.

Barry pulls his girlfriend in for a hug and kisses the top of her hair. "I promise you Cait, we will find a cure."
