I wasn't expecting Simon being Superhoodie!! Fair play to the actor that plays Simon, his acting was very Clark Kent/Superman in the way it was presented. Seeing wierd, shy, geeky Simon we know and the Uber Badass, strong and confident Simon of the future was a nice mix and great acting by him. I don't know if I was seeing things but did of one FutureSimon's clocks say the year 2041?? If so, Simon's looking good for his age, could this mean Simon has Nathan's power?? and time travel, could that mean he has a form of Curtis' power too?? he did say things "change" in the future. Also the idea of Simon's being inmune to Alisha's power mean one of two things to me, either:
1) FutureSimon has Alisha's power too, so it counteract's each others power
or
2) Cause they "fall in love" in the future, and Alisha becomes comfortable and falls in love with someone that somehow makes her power neturalised to that said person?!
Either way something going to happen, that's the reason FutureSimon is here. But atm it looks like his a hero and his here to help but what if he isn't (I hope I'm wrong, cause I like Simon and like the idea he becomes something more, a hero) what if he is actually the reason the Misfits die?? what if he becomes a Supervillain, and the reason he is here, is to change things, with him meeting Alisha, he already changed things in my eyes. Making her fall in "love" with him and later his past self?? Just a thought, atm I'm going to see what happen in next week's ep before I think anymore into that theory.
