The Flash returns tonight (Tuesday, April 21) with a brand new episode after an extended break following the COVID-19 pandemic getting well… bad. You’re living in the world. You know how it is.

Going into the final episodes of season six, we have a lot of questions about what is going on around here. When is Barry (Grant Gustin) going to learn that Mirror Iris (Candice Patton) is not truly his wife? Will there be more mirror doppelgangers? Can Barry and Team Flash build a new Speed Force? We have a lot of questions.

Gustin talked with TVLine about the final four episodes of the season and teased what we can expect.

So when will Team Flash get the artificial Speed Force going? Well Gustin said it will take time and come with a price tag attached. “[T]his artificial Speed Force isn’t going to come together as quickly as we would like it to. And when they eventually do find a way to get it to work, it comes with a pretty big sacrifice for the team.”

The new episode will see the fan favorite (and ever creepy) Rag Doll (Troy James) return. Gustin said that James does his thing a lot on set. “But it’s not just during the takes [that he does that], he will just randomly walk toward you [backstage] in a spider crawl. [Laughs] He’s the nicest, most friendly dude, but it’s terrifying once he has that mask on and he’s bending all over the place.”

Rag Doll also sees Barry and his loved ones at odds with each other on how to handle his finite speed. “The team doesn’t want Barry to waste his speed, that’s an element for sure, but also Joe is in some serious danger and gets harmed in the process. I don’t want to spoil too much, but the dynamic of the West family and Team Flash is going to be altered for a while because of what happens with Joe and Rag Doll.”

And what about Iris? Surely, Barry is realizing something is up with his “wife”. Gustin said that with everything going on Barry has been distracted, but things are coming to a head soon.

“It’s a combination of things. It’s a little bit of the stuff she says, but more an emotional connection that’s lacking or not consistent with what they have always had. Barry has an epiphany moment where he shares all of his suspicions with Cecile, and the writers gave me a really fun scene for when it all lands, where I convey all these ideas about what I think is really going on. We had a lot of fun with it.”

As for their finale? Gustin says that while “Success Is Assured” (6×19) is not the finale that was planned for the season, it will leave audiences with a pretty good cliffhanger.

“There was going to be a big Thawne cliffhanger at the end of what this season would have been, but that’s not going to be the cliffhanger we get. [Episode] 619, “Success Is Assured,” is going to end up being our finale, so we’re going to have a different cliffhanger than originally planned. But the cliffhanger at the end of 619 does serve as a pretty good finale.”

The Flash airs Tuesdays at 8/7c on The CW.
