I could not find Jack’s room number on any of the Supernatural Wikis or Google searches, so if anybody else needs it this is from 13×03 Patience.

The Wikis have already noted Mary’s room was 15, Dean’s room is 11, and Sam’s is 21. How cute is it that Jack picked the room closest to Sam’s (I assume by number). Or the room closest to the kitchen which is 23.

Who do you think Jack loves more, Sam or food?
