To say hello to some old favorites, Flash fans will have to bid a temporary adieu to some familiar faces.

Barry Allen (Grant Gustin) will take on the time-twisting events of Flashpoint this fall, and his efforts to rewrite history will result in a little cast shake up. Those of you wishing to see Harrison Wells (Tom Cavanagh) or Jesse Quick (Violett Beane) will have a long wait.

"[They will return] a little bit latter in season 3," executive producer Andrew Kreisberg told TV Guide Magazine.

Don't worry, however; Earth-2 Harry and his daughter will be well worth the wait.

"How they come back an why is going to be fun an cool," Kreisberg promised. "Fans are going to be jazzed by it."

Harry might be MIA, but that doesn't mean Cavanagh won't find his way into the premiere. The actor will return as a series regular, and considering his masterful ability to play any iteration of Wells the writers throw at him, we're hopping that the new timeline will give us a little extra time with the original Earth-1 Harrison.

"Details on next season are being kept tightly under wraps, but I can tell you that Tom Cavanagh will be back as a series regular for season 3," Entertainment Weekly promised. "Consider this: If the show does indeed move forward with Flashpoint, then the Reverse-Flash never killed Earth-1 Harrison Wells and his wife, meaning we could see the original Wells next season. Maybe. Hopefully."

DC fans should enter season 3 with one caveat - The Flash always puts it's own spin on classic tales, and the series' adaptation of Geoff Johns 2011 staple will be no different. Carlos Valdes (Cisco) has encouraged devout readers to keep an open mind.

"I think I can say this without a doubt: wherever we go from here, it's going to be unique and it's going to be different and it's going to honor the original chronology and the original lore while at the same time, writing a new spin on it," Valdes told Comic Book. "I think it's that spirit that's allowed our shows to do as well as they do, so I ask the fandom to have faith."
