Syd nodded in understanding, remembering the nerves of Kerry before, and that she had shared as well when they were stuck in the terrible mind palace of Clockworks, fighting against imagined monsters and facing off with Lenny and the Eye both. "I don't blame her." She reassured Carey, though did rub absently at her shoulder. There would be a ripe bruise there later.
Worst case scenario. Well, fuck. Which possibly meant that they wouldn't be able to count on Oliver pulling through in the end. But the fact that he had set up the elevator as he did, sciencing the shit out of it even with dna of the dead. "You thought this might happen. The time travel." Which meant that he hoped that time could be fixed too.
"When did this happen?" What sort of timeframe were they looking at? How fast would they have to act if, when, they returned? She returned the look, frowning the way he had been just moments ago, each deepening just a little as she learned another piece of the puzzle. But to be told of your own death, that earned a wide-eyed sort of look. It was one thing to know of your mortality, to accept that it could very well happen in the scheme of what was yet to come. But to be told of it was another thing entirely.
"It's here still, looking. He--" she started, stopping briefly and turning to Carey. "David -- my David," there was no time to be bashful of semantics. "He could feel Farouk. I caught a glimpse too." She continued walking, following Carey, listening.
So. What did they have? Two Carey/Kerrys, herself, and two Davids. ..Two Davids.. That could be something. If they could keep present David from becoming like future David, and bring future David back. And keep the universe from exploding by having temporal copies of the one of the most powerful brains like ever. And keep from said powerful brains lighting their locations up like fireworks from one of the other super powerful brains. Again. Easy. No problem.
"Do you know anything at all about time travel? All I know comes from movies and a marathon of a season of Doctor Who."
