In the next episode of "The Flash," Barry Allen a.k.a. The Flash (Grant Gustin) has second thoughts about their unassuming suspect Devoe (Neil Sandilands).

The trailer for the upcoming installment titled "Therefore I Am" was just recently released and showed Allen telling his team how much he distrusts their latest person of interest Devoe. "This guy, he feels more dangerous than all the others combined. You don't believe me? Guys, I'm telling you, he's not what he seems," Allen says to them with concern. Apparently, Devoe has some sort of ability and is shown catching drops of water floating upwards in slow-motion. Allen has the suspicion that the perpetrator may have been watching them for weeks. Therefore, the speedster does his own digging but is apparently caught harassing Devoe who files charges against him.

"This guy wants us to think he's unassuming but he's not," Allen tells his fiancé and coworker Iris West (Candice Patton) who does not agree with him. It seems that the Flash is the only one who believes that Devoe has a nefarious agenda in mind. "Don't you see what's going on?" Allen asks Cisco Ramon (Carlos Valdes) and Harrison Wells (Tom Cavanagh). However, Ramon tells him not to do anything that he might regret later. It remains to be seen if Allen will be able to convince Team Flash that Devoe is really up to no good.

In the last episode, The Flash went up against Mina Chayton a.k.a. Black Bison (Chelsea Kurtz). She killed a couple of people who were stealing from her Indian tribe but Allen was able to stop her eventually and contain her power of animating non-living objects. Team Flash saved the day once more.

"The Flash" season 4 episode 7 will air on Tuesday, Nov. 21 at 9 p.m. EST on The CW.
