‘The Flash’ Episode 19 Preview: Central City Turns To Starling City For Help With The Investigation Of Dr. Wells

Ready for another Arrow/Flash crossover? Just last week, in Episode 18, “All Star Team Up,” Felicity and Ray stopped by S.T.A.R. Labs to get some assistance with his ATOM suit and helped stop the Bug-Eyed Bandit, as Cisco and Ray named Central City’s latest threat. This time, the crossover is happening in Starling City, as Joe and Cisco are heading that way for some help when it comes to Dr. Wells.

At the end of Episode 18, Barry and Joe brought Cisco and Caitlin in on their investigation into Dr. Wells and told them he’s the Reverse Flash. While Caitlin found that hard to believe, Cisco told the others about the dreams he’s been having – the dreams he’s been having while he’s also awake – in which Dr. Wells is the Reverse Flash and kills him. Yes, Cisco is somehow remembering a timeline that never technically existed once Barry traveled back in time.

These two shows are no strangers to crossovers; in fact, the preview for the rest of The Flash Season 1 shows Oliver Queen by Barry’s side (and it also revealed a big spoiler about what’s still to come in Arrow Season 3). Now, “Who Is Harrison Wells?” sees Joe and Cisco go to Starling City to get Captain Lance’s help with their investigation into Dr. Wells, and while they’re there, Laurel turns to Cisco for a favor. (Get ready for the Canary Cry.) Meanwhile, back in Central City, Barry has to deal with a metahuman, Hannibal Bate, who can transform himself into every person he touches, including Eddie, Iris, Caitlin, and even The Flash.

This crossover is going to show another side to Captain Lance, as Paul Blackthorne told Collider.

“He got to bond with a contemporary, who is another middle-aged man with a daughter, and talk about life on that level. He got to have a cup of coffee and a chat with what could be a really good buddy. It was nice to see that side of Lance’s character, as well.”

Considering Lance isn’t winning himself any points with his actions on Arrow at the moment when it comes to Oliver, this might be the perfect time for that too.

Den of Geek has posted the trailer and producer’s preview for the episode. The promo offers a look at the team realizing that Dr. Wells is a different person – and finding the real Harrison Wells’ body. Is that going to be enough proof for Caitlin? Watch the Flash Episode 19 promo below.

The producer’s preview begins with Joe explaining he and Cisco are heading to Starling City to investigate the car accident that took Tess’ life.

“The team, now that everybody understands just how dangerous Harrison Wells is, is really on the case, trying to figure out who he really is and what he’s up to,” executive producer Andrew Kreisberg previews.

As for the villain-of-the-week, Kreisberg explains that “no one really plays him, no one specific, he’s sort of played by everybody who’s in the episode at some point.”

Because of this metahuman’s ability, it is essential that he doesn’t touch Barry while he’s The Flash if he wants to keep his secret from the world. Watch that preview below.

The Flash Season 1 airs Tuesdays at 8 p.m. on the CW.
