Uh. Big guy, black hair, blue suit with a red cape? Decent guy. He dropped me off at my house. Well, my roommate's house. I guess it's more his than it is mine.

[Kind of a weird clarification to make, maybe, but it makes sense to her, at least.]

He said before he bailed that his name was Kal.

[And his other name is Clark, and he is in fact her roommate, but she's not technically lying by not confessing that. She's just not volunteering everything she knows about him, and technically Damian had only asked her to answer what he looked like.]
