Eight was light--almost worryingly so. Which was odd, because he didn't seem as thin as his later incarnation. Still, he was very light and very warm.

Jack really didn't even need to let the TARDIS know he was looking for someplace to put the Doctor. Corridor lighting and door placement guided him quickly enough to a room that looked and felt ... restful. Not terribly personalised, holding only a bed of esoteric design and insanely comfortable construction, but restful nonetheless. Airy and peacefully lit for an indoor room.
