Last week on The Flash, the team thought that they had solved the issue of the Black Flame when they discovered that the mysterious was Ronnie Raymond (Robbie Amell), Caitlin Snow’s (Caitlin Panabaker) deceased husband and former half of Firestorm. And, for a moment, it looked like things might have a happy ending. Caitlin was able to bring Ronnie back and it seemed as though the team had not only saved innocent lives in Central City from Black Flame, but also saved their old friend as well. Unfortunately, the end of the episode revealed the truth: Ronnie Raymond really is still dead and what returned instead is Deathstorm, who revealed himself to a horrified Caitlin at the end of the episode. Now, The Flash’s showrunner Eric Wallace is teasing what’s next — and suggesting that fans go back a couple of seasons for some big clues as to where things are going.
