"The Flash" Season 3 premiere on October 4, but we'll see him in Episode 2.

In the meantime, Entertainment Weekly shared the first photos of Felton in character as CSI tech Julian Dorn:



Felton told EW he hopes to make a Harry Potter joke or two during his time on the show. He knows Cisco (Carlos Valdes) is more known for the pop culture quips, but "maybe he should misquote something and I could correct him." DO IT.

Executive producer Todd Helbing described Felton's Julian Dorn as a direct result of the Flashpoint alternate universe which created at the end of Season 2. "Barry's had that lab to himself, but now he's got to share it with this guy, who doesn't really like him and is kind of prickly."

Felton will debut in Episode 2, called "Paradox," which airs October 11. Here's The CW's synopsis:

"THE AFTERMATH - Barry (Grant Gustin) realizes the effects from Flashpoint are much greater than he thought. Meanwhile, Barry meets new co-worker Julian (Tom Felton) and is surprised by Julian's immediate disdain for Barry."
