If you're thinking that a blitz from the Rogues this week is an awful lot of action to open up to when there are a lot of dangling character threads left to address on The Flash, you don't have to wait too long to get some resolution.

That's according to Grant Gustin, who told IGN in a new interview that the upcoming episode featuring Peek-A-Boo is a very different kind of episode.

"Yeah, that was… What is that, episode twelve?" Gustin said. "That's a different kind of episode. I liked it. I hate giving away too much, but yeah, that was a different kind of episode because that episode was about relationships, in general, between our villains and our regulars. I can't give away too much about that storyline because I don't want to and most of her stuff is with her partner, her villain partner/boyfriend character. I wasn't there for much of it but it's a really interesting character. It's really different from any other villain we've had on the show. It's one of the ones you kind of feel for. That whole episode focuses on relationships between all of our characters."

The Flash returns from hiatus with new episodes starting tomorrow night at 8 p.m. ET/PT on The CW.
