Well since the teams ahd already left for the next leg (it sounded like that from There speaking), and we know that the Pit Stop was at least a 24 hour one if not longer. And that they finished ont he fourth. Its very likely that Teri & Ian took a full nother day to get to sequesterville. That would put them probably arriving on the 6th. And they would have needed less flying time back home then those who went through Guam, so they probably left ont he 16th or 17th, I would think. But thats just an educated guess.
