Harper doesn't know that Lucie hates him. He's only just found out that this is the roommate. (He really needs to start dropping by to say hello.)

"Chief engineer and a genius. I'm the one they look to when everything is all going wrong an they need something making to save the day." He was getting a little carried away. "I help save the day a lot."

He pauses, but the quiet only lasts a moment, no such luck at getting Harper to be quiet so long.

"You know he hasn't mentioned you to me. Which is a shame."
