The Flash stars Tom Cavanagh and Candice Patton preview the upcoming Arrow spinoff in new promotional videos.

Previously, Cavanagh (Harrison Wells) previewed the S.T.A.R. Labs team that looks after Barry in his coma. Now, he teases Barry Allen’s seemingly impossible abilities:

“Barry’s exhibiting things that are not possible and yet are happening,” Cavanagh explains. “Our team, at least initially, seems like we are just trying to examine and determine why he can do the things that he can do.

“But,” he teases, “there’s much more to it than that.”

Next, Patton (Iris West) has a short preview of her character’s relationship with Barry:

“She’s known Barry since they were kids,” Patton teases. “They were friends in school and they became really close after Barry moved in with her and her family after his mom passed away.”

She adds, “They’ve just been friends for so long, I think Iris is maybe a little aloof to the idea that Barry has had these feelings for her for so long.”

In Barry’s Arrow appearance, he told Felicity that he knew something about having feelings for someone who didn’t return them — and clearly he was referring to the lovely Iris West.

Barry and Felicity, however, also had strong chemistry, so it will be interesting to see if that relationship plays into the Flash story at all.

The Flash will air Tuesdays at 8:00 p.m. ET on The CW this fall.
