Since what happens on The Flash directly affects what happens on sister series Arrow and Legends of Tomorrow, however, it was never likely that we’d be seeing a whole season of Flashpoint.
This could directly go against the rumors that have recently flown around noting that Supergirl might be able to become a part of The Flash, Arrow and Legends of Tomorrow’s universe thanks to some clever writing in Flashpoint.
As it stands, Arrow and Legends aren’t expected to go through massive changes to accommodate The Flash, so a shortened Flashpoint could mean even slighter ripples across this universe.
The Flashpoint exercise is only for a couple episodes before it comes back in.
