The Flash S01E09 Still - H 2014

[Warning: This story contains spoilers for Tuesday's midseason finale of The Flash, "The Man in the Yellow Suit."]

If you thought The Flash midseason finale was big, just wait.

Yes, we now know Reverse Flash is … Dr. Wells (Tom Cavanagh)! That's one mystery answered, but there are many more to explore.

"There are a couple of big things happening in episode nine. While they come to a dramatic conclusion, these events are going to echo throughout the rest of the season," executive producer Andrew Kreisberg tells The Hollywood Reporter. "When we come back, people are going to be excited."

The midseason finale gave us epic confrontations between Barry (Grant Gustin) and Reverse-Flash, who masterfully taunted our hero. How badass was it when he said "If you want to find out, you'll have to catch me," or when he went Hannibal Lecter when he was captured in the lab?

We also got a little closure on Ronnie (Robbie Amell), who revealed his superpowers (and that he's alive) to the team. All this stuff is building to even greater epicness to come. First on deck: a supervillain team-up.

In a chat with THR, Kreisberg talks about the potential for Barry to join forces with other superheroes, what he's learned from Arrow and what else to expect from the rest of the season.

You've covered a lot of ground in these first nine episodes. Did you ever feel like you weren't holding enough back?

TV moves at a much faster pace now, and it's one of the things I've learned from [Arrow and The Flash executive producer] Greg Berlanti. If you get really excited about something, you can't always wait because there might not be a "then" to get to. We really wanted this show to be exciting and be a roller-coaster ride, and part of that is you can't just tick off mysteries and never solve them. For us, it's really important to reward the audience for faithful viewership. We want to set up new mysteries and reveal how they affect all the characters.

What are we looking at when we return?

The biggest thing is in episode 10, we have our first team-up between Captain Cold and Heat Wave. We have a Prison Break reunion with Dominic Purcell and Wentworth Miller. There are a couple of big things happening in episode nine, and while they come to a dramatic conclusion, these events are going to echo throughout the rest of the season. When we come back, people are going to be excited.

Oliver Queen has a team of superheroes working with him. Will Barry be getting any superfriends?

We're going to get a really good look at Firestorm in this episode, so that's one. As the season progresses, we've seen from the crossover that Barry does play nicely with others, so the idea of having him team up with other people or people we're introducing is a possibility.

This was such an ambitious episode. How did you manage to get an extra two-minute running time for it?

That really is a credit to The CW. They are so incredibly supportive, and for them to give us that extra time is amazing to us. They saw an early cut of the show that was considerably longer, and they said they wanted to keep as much as we can. Without generosity and spirit on their part, some of the really special moments would have been lost.
