User blog comment:ArtDraw12/TD Theories: Who May Return in Potential Future Seasons?/@comment-455481-20161008050755/@comment-11883116-20161008130531

There is no one under confirmed though. Although some could be easily assumed to be semi-confirmed, like Dave and Sky whose plot is clearly not over yet and Lindsay and Tyler for whom the creators appear to have some plot planned (otherwise why would they say they broke up off-screen?).

Yeah, likely ones wont' necessarily return the very next time, but are to be expected to return in one of the nearest seasons.

Also, keep in mind the creators may always shock us. Who'd expect Sam on TDAS? And he did nothing. Sure, I analyze them based on their potential. Sure, with 84 contestants they shouldn't let someone who'd do nothing return. But they can always surprise us.
