Part two of The Tomorrow People‘s mid-season finale promises to be a nail-biter. Between John being captured by Ultra, and Stephen’s determination to find some way to get to “limbo,” there are many things that could go wrong for our favorite evolutionary friends.

EW has an exclusive promo for the fall finale, which shows Stephen discovering a video of the Thanatos trials (featuring his father) and John finally fessing up to killing Roger when he was under Jedekiah’s orders. However, that doesn’t seem to stop Stephen from thinking he can still find his father. All he needs to do is almost die?
