Robin was starting to actually feel a little bit guilty about not reaching out to Lisa right when she'd come back from the dead. (God, that didn't sound any less melodramatic the more she thought or said it.) If they'd switched places, she would've wanted to hear from her right away, too. "I don't know if there's really a normal reaction to what happened, but thanks anyway."
She raised her eyebrows at the mention of Lisa's roommate, her curiosity piqued. "He hit you with his car and you're still friends with the guy?" Obviously there was something more there that she didn't know, but Robin didn't think they were at the point where she could pry or ask questions.
"I might want to look into those apartments in the future, although I've kind of gotten attached to the ghost dog that lives in my room." Maybe she could get one with Ted, Barney, and Lily. That way she could keep an eye on them.
