The Flash - Season Finale Post Mortem - Bosses on Heartbreaking Death & More

When did you know Eddie would make this sacrifice?

When we decided to name him Thawne, we hoped the audience would suspect Eddie was the Reverse-Flash because of his last name. We always knew Eddie would be his ancestor, but we weren't quite sure how we would end the season. The way things were moving forward, it felt like it was the best thing to do for his character. Like with Colin Donnell [whose character Tommy died in Arrow's season one finale], it was literally the worst thing we could do to ourselves as writers, producers and friends, because we all love Rick so much both personally and professionally, and we think he's crushed it as Eddie all season. We've all become very close. It's one of those terrible things. The story sort of tells you what it wants to be and as much as it broke our hearts, we knew this was the way the season needed to end.

What does this mean for Tom Cavanagh's future on the show?

Tom Cavanagh will be back. That is not in question. Tom Cavanagh will continue to be a regular.

You've said season two will introduce more Speedsters. Is that going to be a major theme akin to the Rogues in this season?

Yeah. We are going to introduce a few more speedsters next year and a bunch more villains. How they and those villains come about is part of the surprise of season two. We're really excited. [Executive producer] Greg [Berlanti] and myself and [executive producer] Geoff Johns and the writers, the cast, the crew, the directors — we are so proud of this season of television. It really is a high mark for all of us and we feel a great deal of pressure and anxiety to live up to it, because it's been so well received. As proud as excited as we are about everything we've done this year, we really are just as proud and excited for all the things we are planning coming up and hopefully people will continue to take this ride with us.

We got a brief glimpse of Matt Letscher before Reverse Flash fizzled out. Will he be a part of the show moving forward?
Yeah. We hope so. Greg [Berlanti] and I both worked with Matt on Eli Stone. We’re friends. We’re such huge fans. The idea of Eobard Thawne having essentially stolen Harrison Wells’ body was an idea that we came up with midstream. That wasn’t always part of the conception. What’s wonderful about it is now it allows us to have two tremendously talented actors both playing the same villain. When the Reverse Flash returns, the face that’s underneath the hood can be one of two faces now.

Let’s talk about Barry running into the singularity in the final moments of the finale. Are you planning to pickup right where season 1 left off?
We’re mapping out the season. The circumstances in which we come back will hopefully be surprising and entertaining. There are a bunch of questions that were left unresolved at the end of the season and they’ll be resolved in the premiere. But how that happens won’t quite be the way people expect. Hopefully the unexpected is what people have come to expect from us.

The entire city is being sucked up into this singularity.
I hate when that happens!

Should we be worried about time getting altered in the process of Barry fixing things?
When you open a singularity above a city, you should be worried about anything and everything that happens. Part of the fun of The Flash is when you have people dabbling in sci-fi physics, they’re significantly altering the world. We established in the finale that the entire series of The Flash is, in itself, an alternate timeline that’s been skewed from the real one. Wells setting off the accelerator created all the metahumans, and the results of the singularity will also have long-term effects.
