Fans lost Ronnie Raymond (Robbie Amell) in the Season 2 premiere of "The Flash" on the CW. Ronnie combined with Dr. Stein (Victor Garber) to form Firestorm and create a blast of energy to neutralize the black hole threatening Central City. Barry (Grant Gustin) was able to save Stein, but not Ronnie. Is the fan favorite character, and Caitlin's (Danielle Panabaker) husband, really gone?

"Well, you’re never really dead when you’re on 'The Flash', a TV show where there are universes and time travel," Kreisberg told Entertainment Weekly Wednesday. "He was, in fact, killed in that moment, but that doesn’t mean that we’ve seen the last of Robbie Amell on this show. Certainly, [producer] Greg [Berlanti], Robbie and I all hope to work together on 'The Flash' again."

So, it sounds like Ronnie will return, at least in some flashbacks, in future episodes. But why kill the character in the first place?

"Part of the decision was Robbie’s burgeoning film career," says Kreisberg. "He’s on his way to being a very big star, which he completely deserves both professionally and personally. We didn’t want to stand in the way of that. As always, sometimes those tough decisions yield the best storytelling because obviously Ronnie’s death has a major impact on all the characters, Barry, Caitlin (Danielle Panabaker), Professor Stein. It also gave us a lot of our storytelling as we move forward. Everyone knows there’s a second spin-off coming with 'Legends of Tomorrow'. They know the Firestorm legacy is far from over, so it just gave us a lot of rich storytelling to pursue."

That Kreisberg would mention "Legends of Tomorrow" is interesting. Firestorm -- the combination of Dr. Stein and Ronnie -- will play a major part in the spinoff series, but though Victor Garber (who plays Stein) is confirmed to be a part of the cast, according to Cinemablend, Robbie Amell is not. The trailer for the series skirts the controversy, only showing Stein and a post-combination Firestorm engulfed in flames, leading fans to question if Stein learned to become the character solo or if another actor had been cast in the role of Ronnie.

Will Robbie Amell join the cast of "Legends of Tomorrow"? Only time will tell. Hopefully, though, he will at least show up again on "The Flash."

"The Flash" airs Tuesdays at 8 p.m. EDT on the CW. "Legends of Tomorrow" premieres in 2016.
