Arrow Season 4 Finale: 12 Big Questions We're Asking After 'Schism'

12. Will Arrow Be Affected By The Flash?

Ok, this isn't The Flash, so what happened on that finale wouldn't normally have much to do with this one. But in this case it's a rather pertinent issue, because Barry Allen's actions should theoretically have consequences for the entire CW/DC roster.

Although it's not quite clear just how much the timelines of the two shows match up, there's only a couple of weeks difference at most, and Barry's choice is so potentially game-changing that you'd think it would have to impact Arrow and Legends of Tomorrow. But will it?

It's one thing for The Flash to mess around with its own timeline, but a much bigger thing to do so with that of other shows - ones where fans might not even watch The Flash. That's a riskier proposition, but similarly diffiuclt to explain it not happening, so how they'll address that will be interesting to see.
