If Owen spoke Raptor (ok so maybe he liked to think he did, better than the average human anyways) he could have clearly deduced the reason for the pitch in her cry and growls. She was upset, that was obvious, but when he saw her clearly and she was readying for a potential threat it wasn't that hard.
"Hey," he said gently, clearing his dry throat from not speaking or drinking for very long. And from being a human raisin, thanks a lot, vampire bitch. "Easy girl. The crazy is gone, at least for now. It's just us." Maybe he shouldn't have said that because after a day ago Owen assumed it was just him up until he was being leeched.
He held out his hands with his palms open to calm her slowly bringing his wrists down and even taking a few light steps towards her, leaning his hip against the ledge of the stairs. "I'm just checkin' up on you." She didn't look like she was missing any meals, was free of scars or injury, so that was good. In theory. "And to tell you that apparently we've got to watch out for fucking vampires." Owen snorted. If he went on blabbering like he normally did, talking to her like she could understand every damned thing he said, then it would maybe ease her alertness.
