How would you feel if Iris West really did die when it comes time to see the episode?
I'm of two minds on this . . .
On the one hand if she dies Barry will be free to focus totally on his "powers" and improving himself in that regard. It would also set up an interesting situation in that Joe would blame Barry for not saving her, which would create an interesting and tense dynamic within team Flash and in their relationship.
BUT Iris has also grown on me and she appears to be a mainstay in Barry's life and he is motivated to be a better hero with Iris' love. If she dies who will be the "love interest?" Caitlyn, the former cop (will she return- can't think of her name now.) or an as yet revealed character?
