During the two-part Arrow/Flash crossover event last season, we saw Oliver, Felicity, Diggle, Thea, Laurel, Cisco, Caitlin and a whole city get vapourised when Ollies mind wasnt on the task at hand, leading to Vandal Savage laying waste to a whole bunch of innocents. Luckily, The Flash was on hand to rectify things by travelling back in time and taking a different approach to what hed seen play out previously. With that said, is it down to this time travel that Felicity is in a wheelchair? After all, altering timelines causes certain problems down the line, and Ollie believes that this could be just one of those problems. Then again, in the initial future that we saw play out, Felicity was part of those turned to dust by Savage. Even if shes in a wheelchair now, surely thats better than, yknow, actual death?!
