Warning: Spoilers ahead for an upcoming episode of The Flash.
Additional reporting by Lucas Siegel.
During a panel at Heroes and Villains Fan Fest in New Jersey this weekend, The Flash recurring guest star Robbie Amell dropped what seems to be a huge spoiler.
For those who don't remember, his character -- Ronnie Raymond -- died in the Season Two premiere, but recently The CW confirmed we'll see an evil, Earth-2 version of Ronnie as Deathstorm in an upcoming episode.
"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," Robbie Amell said at the Flash panel at Heroes and Villains Fan Fest in New Jersey.
Of course, it's generally assumed that the episode actually takes place on Earth-2, so the question then becomes whether it will be an "actual" series regular or whether he'll get to kill an actor who is also a series regular, because he takes out the Earth-2 version of somebody.
In the "A little of each" column, of course, he could kill Harrison Wells -- but that would be a curious move, since everyone is assuming that Deathstorm and Killer Frost are in league with Zoom, who currently is using Wells for his own ends.
The Flash airs Tuesday nights at 8 p.m. ET/PT on The CW.
