There's no question that she cares about Poe, even if she can't define those feelings exactly. But the devastation she'd been prepared to feel when/if he'd rejected her is proof of that. And it's a lot, she almost feels dizzy with it. He goes on to say that humans aren't the be-all end-all of anything and she opens her mouth to say more, to explain with delicacy what it means to be a vampire before she remembers herself.

Her eyes flicker to where she thinks a camera sits. Her voice raises a little, "We should go inside. Maybe you need to lay down for a bit." She wonders how much she might get punished for exposing herself already but... if she can just talk to him for a little while, without worrying about what's being said. She hopes and assumes, he'll catch her meeting and she doesn't care if whoever is watching on the camera does too. They can't see what happens in their minds.

Also, despite taking these few selfish moments to sort her shit out, she is a little worried as to why he just fell backwards.
