No, he's not expecting that. Jason shifts forward, using his free hand to pull up Barry's upper lip. And has to stare because, yeah, those are...

"Okay, that shouldn't have happened."

Because that made sense, Jason.

He let Barry's lip drop, pursing his own. "Right. Yes, you were bitten. You were bitten really badly and, yeah, we nearly lost you. Probably more times than even I know about because it took some time to get here from St. Louis." He took Barry's hand between his, rubbing his boyfriend's hand gently. "You didn't die. You can feel your heart still beating and that wouldn't be happening if you were a vampire."
