Harry Potter's Tom Felton played Julian Albert throughout The Flash season 3, but he hasn't been seen since the team defeated Savitar. What happened?

Julian Albert, also known as the villain Dr. Alchemy, was last seen in The Flash season 3 finale before going back to London between seasons and hasn’t been heard from since. Played by Tom Felton (best known as Draco Malfoy from the Harry Potter movies), Julian’s presence on Team Flash was one of the changes made by “Flashpoint” in season 3. After preventing his mother’s death at the end of The Flash season 2, Barry Allen resets time mostly back to what it was supposed to be. One of the changes is Julian Albert working with the Central City police and Team Flash.

Julian came to Central City looking for the Philosopher’s Stone, which he thought would be able to bring his sister back to life. While there, he came under the control of Savitar, the main antagonist of that season of The Flash, and went around under mind control as Dr. Alchemy, giving metahuman powers to people who had them in the “Flashpoint” timeline. Julian also played a big role with the team for the rest of the season, even after his time as Alchemy was over. He eventually became close with Caitlin, including trying to find a way to suppress or cure her Killer Frost persona.

His disappearance at the end of The Flash season 3 came as a bit of a surprise since it wasn’t announced until after the first trailer for The Flash season 4 released. Since his final appearance, he's only been mentioned once — in The Flash season 4, episode 1. Specifically, Joe West (Jesse Martin) says that the crime lab has been swamped ever since Julian left to go back to London, leaving them down another CSI as Barry was trapped in the Speed Force. Presumably, Julian could be around somewhere on Earth-Prime, but there’s no confirmation yet. Tom Felton has shown interest in coming back to the show to reprise his role, but so far there’s been no movement on that front.

Why Julian was written off the show is unclear and has never really been addressed. Julian’s departure in the time jump between The Flash seasons 3 and 4 was given a weak story explanation. Tom Felton and the rest of the cast and crew seemed to get along, and there was no indication Felton chose to leave for any specific reason. Even though he was part of season 3, the most mixed season of The Flash, his presence was one of the better-received parts of the season, leaving his disappearance from the show a bit baffling.

The Flash's story has come a long way since Julian's departure, and while there didn't seem to be much room for the character's return in previous season, it's something that could happen in season 7 or later given that the world has changed due to Crisis on Infinite Earths. Perhaps Earth-Prime's Julian never worked with Team Flash or perhaps something changed at some point that would allow him to return down the line. However it could happen, The Flash should certainly bring back Julian.
