It's official: Tom Felton, who played the notorious Draco Malfoy in "Harry Potter," has joined "The Flash." Though the news broke only yesterday, Felton has taken to Instagram to thank fans for their outpouring of enthusiasm about the casting.

In "The Flash" Season 3, Felton will play series regular character Julian Dorn, "a fellow CSI at the Central City Police Department who suspects there's more to Barry Allen than just his good guy reputation." The character sounds very similar to one described in an earlier report, which revealed that "The Flash" was looking to cast "Barry's slightly older, slightly geekier contemporary, a guy who is as smart as he is intuitive. As such, this newcomer doesn't buy Barry's nice guy routine and sets out to learn what he's hiding -- all while concealing some secrets of his own."

In the Season 2 finale, Grant Gustin's Barry Allen went back in time and prevented his mother's murder, triggering a famous linchpin event from the comics. While we've yet to see how this massive change in the show's timeline will affect the series as it moves into its third season, "Flashpoint" -- the title of the Season 3 premiere episode -- gives fans a major, major hint.

The major DC Comics event from 2011 of the same name saw Barry Allen trying to navigate a totally altered world -- one wherein his mother Nora was alive. "Flashpoint" also served as the lead-in to DC's New 52 relaunch, the effects of which are still being felt today as part of DC's current Rebirth initiative.

Starring Grant Gustin, Jesse L. Martin, Carlos Valdes and more, "The Flash" returns to The CW on October 4 at 8 pm EST.
