Wonder if there's a microwave inside that satellite/time machine
Great episode, once again! As everyone else has already said, it probably wasn't a surprise for anyone that Suzuha was John Titor... the scene was still very well done and made me want to know more about Suzuha's "past" which is the future for current Okabe and friends.
However, it would fit that Suzuha is the daughter of Daru and that's how he is so familiar with Okabe's past. It'd be pretty random if Suzuha ended up being just some soldier that voluenteered for the time travel mission.
But, we still don't know why Suzuha is here. She has said that she is here for her father but I doubt that's the truth. It could be Suzuha that killed Kurisu in the first episode but these are only guesses.
Wondering who the FB is. Probably someone already introduced to us like Kurisu's father or Feyris' dad.
Will be fun to see what happens if Okabe manages to travel between the main worldlines... things could be way different in other worldlines and therefore things could go very badly wrong.
