Keeping this in consideration, does Iris actually die?
After years as a prominent presence in the Flash's life and Central City, she is killed by Professor Zoom during a costume party. Zoom vibrated his hand into her head, solidifying it just enough to kill her.
Also Know, does Iris come back in Season 4? When The Flash returned for Season 4, Iris was the only one who really flourished during Barry's Speed-Force absence. But the reality is, if you're going to have Iris hanging out at S.T.A.R. Labs all day anyway, give her something to do there.
Likewise, does Iris die in the flash?
Suffering from guilt after accidentally revealing Iris' (Candice Patton) location to Savitar, H.R. Wells (Tom Cavanagh) used the transmogrifier to stand in for Iris, thus sacrificing himself to give Barry a happy ending. Well, as happy as can be at the moment. The good news is that Iris is still alive.
What season does Iris West dies?
Barry Allen has a pretty clear motivation during season 3 of The Flash. Having seen the love of his life, Iris West, die at the hands of Savitar several months in the future, Barry and his friends are pulling out all the stops in an attempt to ensure that doesn't happen.
