Things were going to be tense for a while, even if she didn't quite understand why (maybe Booker's just irate about the Lutece twins' very mysterious manner when he himself was very to-the-point?), but it wasn't discouraging. They both seemed to attempt to be civil when she was in the room, at least.]

That's why I offered to let him stay with me, before you came. It's been a couple of weeks, and he's still talking to himself and forgetting he has to eat. [She sighs and looks away from the shelf and back to Booker.] He did give us the schematic so we knew where to get the whistle. I'd feel responsible if anything happened to him.
