I'm guessing we can pretty much expect every member of the Team to be present and accounted for in this episode. As of right now, there's only one secret left to be confirmed to the audience in-universe: the identity of Kaldur's father. Also, considering what's coming up and how much time there is to finish up all storylines, I would guess that the very final moments of the episode will reveal the identity of the mole - if not to the Team, then at least to the audience.

BTW, actually guessing here. Haven't seen any of the leaked episodes.
