The best spin we can offer is that, having seen (himself see) his love get slain by Savitar in the not-too-distant future, Barry will do all that is in his power to avert that ending. Obviously Barry loves Iris more than anything, notes co-showrunner Aaron Helbing, and now that he has gotten a glimpse of the future, the thrust of the back half of the season is Barry trying to do whatever it takes to save her with critical assists from both Cisco and Iris brother Wally, aka the newly christened Kid Flash. BONUS SCOOP: Helbing warns not to assume that Iris death and Barrys subsequent suffering account for two of Savitars three prophecies. The future is malleable, the EP notes. Anything can happen.
