Kitty didn't jump, but she did look up and blink, trying to focus from words to a face. She blinks again.
Belladonna.
"Uh, hi," she says, and smiles. Kitty decides that comparing this woman with the Belladonna she knows from her time line isn't fair, so she uncurls from her chair a little and adds, "I'm okay. You?"
And she manages to gesture to the chair across from her, indicating that she is welcome.
