1644. How do ppl know for a fact that both Antonia and Iwan decided to leave the show? Since the revelation came about that Superhoodie was Future Simon (in S2) and he told her that he went back in time for her b/c she dies, I think it was pretty much a done deal. It was gonna happen. They could’ve dragged it along all the way, but they were going to have to fulfill that prophecy and have Alisha die. It had nothing to do with the actors lol.
They’ve both been clear for a while now that they were looking to capitalize on the attention they got from Misfits & use that boost to open up other avenues. Frankly I’m surprised any of the original cast is left for season 4.
