Jack is... in, out, and around
Sometime after Jack has moved into the TARDIS, he leaves a letter in the TARDIS library since that's where the Doctor spends much of his time, and the Doctor wasn't available to tell in person when it happened:
He indeed comes by plenty, what with Ianto busy with work and Jack needing some company and entertainment during the day. Sitting around the house watching movies isn't a bad thing, but he's used to lots of action, so he heads out often during those work hours. And it's quite convenient to pay a visit to people living in Holmes's house, considering that the TARDIS is right there in the garden.
OOC: Since various threads got dropped with the Holmes house crowd (Holmes, Iago, Xel, a few with Dora), I thought I'd offer a post to start new threads with them, horray! Feel free to catch Jack around the garden-- or be caught by him!
ETA: Also, got a shiny layout up for Jack and it makes me happy. Yay!
