Olivia's eyes flick to the syringe, and then back to Steve, watching uncertainly for any sign something's going wrong. It's just blood. Super soldier blood with god knows what in it, sure, but she doesn't see it actually killing her. Cortexiphan, though...

"No one's going to die," she says, quiet but firm, her eyes locked on Steve. Cortexiphan's about feelings - she remembers that much from being small and terrified, with a needle in her arm just like this - and he can't think he's going to die right now. He can't.

"She's right. No one is dying." And he's injecting the blood, clearly unconcerned by Steve's words. "Cortexiphan subjects are more resilient than you might think... and we do have more of them than we do of you, Captain."

Olivia looks up at that, glaring briefly. "Thanks. It's really nice to know where I fit in here."
