(Conveniently, of course, up until a moment previous, this was also his space, and thus it's terribly easy for Bob to be cozy in it.)

Just as he's about to lean in for the kiss, of course, there's screaming down the hall.

(And, just outside the door, something really miraculous happens: Peter-Fred actually notices, immediately, with the end result that his startled "Claire?!" is also quite audible.)
