'The Flash' Actor Grant Gustin Takes Things Slow As He Dances With Co-Star Tom Cavanagh While Filming Series In Canada

"The Flash" actor Grant Gustin hammed it up during filming in Canada as he was snapped slow dancing with co-star Tom Cavanagh on Thursday.

The two actors were suited up in their costumes, Grant Custin with his trademark red and Tom Cavanagh with the golden Reverse Flash suit.

"The two actors had a bit of fun with each other as they waltzed on a footbridge in the Great White North and even showed off some moves as Grant spun Tom at one point," said Daily Mail. "On the program Grant plays Barry Allen, alter-ego of The Flash, who is a Central City assistant police forensic investigator before an accident gives him the power of superhuman speed."

Although Grant Gustin's character in "The Flash" only knows Dr Harrison Wells, Tom Cavanagh's character, as the head of the S.T.A.R. Labs, he's actually Reverse Flash, who seems to be responsible for the death of Barry Allen's mother.

In the next episode of "The Flash," there's going to be a lot of awkwardness when Grant Gustin's Barry Allen and his journalist girlfriend, Linda Park, will go on a double date with Iris West and boyfriend Eddie Thawne as they go bowling.

The writers of the show have hinted that Iris might have some feelings for Barry Allen when she appeared to be jealous of his new girlfriend.

"Is this going to be where Eddie realizes that his girlfriend is still holding a candle for Barry, even if she doesn't quite know it? It's possible," Cartermatt.

"One of the interesting facets about this story is that while she has been friends with him for a long time, there have not been many times in there where she has seen him with another woman. This is going to be a challenge for her to not have his attention all of the time, and it may lead to her analyzing her own feelings more."
