As far as CW’s The Flash goes, it has always been said that Flashpoint will have an effect but won’t last all season.
Supergirl season 2 airs Mondays at 8pm on The CW, The Flash season 3 airs Tuesdays in the same timeslot, Arrow season 5 on Wednesdays, and Legends of Tomorrow season 2 airs on Thursdays.
Season 3 of The Flash picked up right where the second season ended — with Barry face to face with (both of) his parents, alive and well.
But Flashpoint or not, there are consequences going forward for Barry for what he did, and those ripples he’s going to explore throughout the third season.”
