"Okay." Barry still doesn't trust himself, doesn't trust whatever has been done to him. Sure he'll sleep over at the Circus with Jason, talk easily with the other vampires, but they were human when they were turned. Metahuman plus vampire equals one hell of an unknown.

It takes the combined effort of Cisco, Caitlin and Jean-Claude to finally determine what was happening to Barry. There were tests that followed and none of them were pleasant, but Barry went through them all without complaint.

He's thirsty though. Drinking cup after cup of water in between the blood tests, speed tests, the MRIs, even the UV lamp test (and that was a relief to know the sun wouldn't hurt him). "Hang on, hang on," he holds up a hand as he goes for yet more water. "I'm a what? Dhampir? I've never heard of that."
