It's funny because, despite all the comments on here, you have Nancy, everybody really, coming out and saying they want him to win. They seemed to enjoy being in the house with him, he's probably a lot of fun; the trouble is, we don't see any of the fun because it's not dramatic enough to make the edit.
Shouting makes the edit, a small bit of fun makes the live feed.
So much as I agree, he's not done much, he does seem to be liked by everybody in there, participates in everything, seems to do washing up, the laundry, etc.
We don't, however, see any of that so, based upon what we are shown rather than how it probably is, I would have to wonder what he will do.
It certainly will change the dynamic of the younger group - perhaps Jeremy will seize the chance to move away from Steph and hang out more with Scotty.
