Bruce doesn't sleep at all, but that's not abnormal; he has followup work to do, and he has to start the process of letting this apartment go - they were probably followed, at least partway, so he sets up a dummy identity for someone Tom was friends with, before they vanished. He goes through his notes, makes more, combs through the network, and a hundred other tasks that don't require he leave this room.

As Tim surfaces, he's talking quietly over his CiD with someone - someone full-voiced and Scottish-sounding, and Bruce (Tom) seems relaxed about it, if typically reserved. Whatever they're discussing is too obscured by his awareness of a potential eavesdropper to be properly picked up, and by the time the younger man is stirring, the conversation has ended.

Quietly, and nearby - "You okay?"
