Also, in addition to Jay Garrick, Patty Spivot and Wall West, we will have a lots of new villains to deal with this season, not to mention Zoom is coming. Oh, I wonder who will play Zoom's character!

Rick Cosnett (Eddie) could play Zoom. The producers did say we haven't seen the llast of him.

Its Eddie with how Barry feels about Eddie dying and saving the city, and Barry blaming himself at what happened to Eddie. Having Eddie be Zoom makes a lot of sense, also something else if Ronnie dies in the winter finale which is also the big crossover that leads into LOT, it would parallel the first winter finale in that one Caitlin said she wished Ronnie had just died that night instead of becoming Firestorm now picture what its going to be like if Ronnie dies in this winter finale?

see I don't want ronnie to die but I guess with the actor not wanting to do a lot it will make sense .. I would love Eddie to be the zoom he will be a part of the world as a meta human plus we don't know where he went after he died and got sucked into the hole

I wonder why and how they will kill Ronnie, because he's only been married to Caitlin and it's not been long. Any theories?

Maybe that'll be the last straw to her turning into KF?

how do you explain Robbie not being in LOT? Stein having a new "other half" named Jay Jackson? Unless Ronnie magically disappears, he is as good as dead.

not sure she'll turn KF this season. Andrew and Greg both said that they wouldn't give us everything right away. This season we have Cisco turning into Vibe.

Ronnie will die in the winter finale I mean come on with them saying big crossover in the winter finale that will lead into LOT, Jay Jackson is the last person Stein wants to share Firestorm with, and let's not forget what they said last spring there's a reason why Ronnie isn't in LOT but they couldn't say why. Really I think Zoom/Eddie will kill Ronnie it may cause a rift between Iris/Caitlin friendship, maybe it will push Caitlin towards her becoming Killer Frost maybe she kills Zoom/Eddie?

Ronnie would die

...the new chapter of The Flash could see a decisive separation of the Raymond/Stein dynamic as each character diverges to explore their superhero potential on their own.

With Garber's move to Legends of Tomorrow, show producers could be paving the way for Raymond and Dr. Stein to explore their own side of Firestorm separately, coming together later to join their powers into a Firestorm of comic book proportions. Yet knowing that Ronnie Raymond also eventually dies in the comics, with the rise of his wife Caitlin Snow as the villainess Killer Snow, the split could also pave the road to Martin Stein's adoption of the Firestorm moniker for himself.
