So you better check yourself before you check out... [Des and Martha]
The Doctor's just been kidnapped and smacked in the face with everything he's done wrong in the past... well, since the warehouse.
Consequently, when he slinks back into the basement, it's with a lot more guilt and contrition than when he left, and all the anger's just gone out of him completely. He walks quickly down the hall to Martha's room, avoiding looking directly at anyone on the way, and stops outside her door.
The Doctor hesitates a second before calling through the door. "Martha?" Whatever Jack said, the Doctor's not convinced she'll want to see him now, and can't blame her if she doesn't.
