Despite the huge blizzard, the Heroes and Villains Fan Fest in New Jersey this weekend continued as scheduled. In attendance was Robbie Amell who discussed his return to The Flash as the villainous Deathstorm of Earth-2. Spoilers follow. "In episode 13, so in a couple weeks, you'll see me as Deathstorm, and Caitlin as Killer Frost. So I get to come back, and I kill a series regular. So there's that, I'm probably going to get in trouble for saying that." Here's where things get tricky. With Barry Allen and the rest of Team Flash journeying to Earth-2 it's likely that they'll be running into their Earth-2 doppelgangers. Does Deathstorm actually kill a Prime-Earth or Earth-2 version of a series regular? Perhaps we'll receive a hint in the next all new episode of The Flash, Tuesday at 8/7c on The CW.
