Grant Gustin (Sebastian) is ditching his preppy Warbler uniform for a bright red superhero costume, and his Glee co-star Darren Criss (Blaine) couldn’t be more excited! We learned a few weeks back that Grant has signed on to play The Flash in the CW’s Arrow, and that the role comes with its very own potential spin-off built in. How cool is that?

Darren, who donned superhero tights of his own on Glee last season, is a self-confessed superhero fanboy, so it’s no surprise he’s so stoked to see Grant land this sort of a role.

On September 27, Darren tweeted a photo of Grant in his Warbler uniform, writing, “I give you Barry Allen, aka The Flash himself! How cool is that?

Just a day before, the slushie-tossing Glee guest star made his first trip to the Arrow set... a fact that his new co-star Stephen Amell (Oliver Queen) was quick to document on Twitter.

“WHOA!!!” Stephen tweeted, “@grantgust got up here in a... ”

Flash? In a flash? We love his sense of humor already. Best of luck on the new gig, Grant. We can’t wait to see you in action!
