The Doctor sits down with them as well, he was thinking for awhile "Yeah sorry about that, has been awhile since we have seen each other," He was smiling "But since I have a time machine we could be gone awhile and still bring him back on the same day, " he chuckled a bit. He knew that he should let Jack talk with his friends a bit before they set off.
He didn't really mind when they set off. "How long has he been gone from here, after you lost him? because hes only been with me 3-4 days.?" he wondered if Jack had been missing awhile.
