I almost sure that time travel or time-something is relevant. It is mentioned in the subliminal messages of the OP, just like many of the powers our characters have. Maybe the wet guy can travel in time, so that’s how he finds out who will have powers, and where he is/was/will be.
It’s a strange fact that he was right in the crushing scene, isn’t it?
Again: Time is relevant imo, a clock in the OP, subliminal texts “time lapse”, long exposure photos in the ending. But we’ll have to wait… the show seems to talk about Fate, right from the early trailers. Only time will tell…
