THE FLASH
>Barry Allen (Grant Gustin) has been happily living in the Flashpoint timeline with his parents Henry (John Wesley Shipp) and Nora (Michelle Harrison) for three months, although he retains his memories of the original timeline.
>Barry and Iris West (Candice Patton) are only childhood acquaintances who reunite as adults, upon which Barry pursues a relationship with Iris.
>Although they're coworkers at the Central City Police Department, Barry isn't close to Joe West (Jesse L. Martin), who has grown estranged from both of his children and is at the lowest point in his professional and private life.
>Wally West (Keinyan Lonsdale) grew up with Joe and Iris, and is the Flash, although his identity is a secret to his father. Meanwhile, Eobard Thawne (Matt Letscher) is still alive and being kept in captivity by Barry.
>Cisco Ramon (Carlos Valdes) is now the wealthy and snobbish CEO of a technology corporation, while the whereabouts of Caitlin Snow (Danielle Panabaker) and Harrison Wells (Tom Cavanagh) are unknown.
>Julian Dorn (Tom Felton) is a forensic scientist for CCPD and Barry's rival, who believes Barry hides dark secrets behind his "nice guy" façade. Although Julian has been working with Barry for years, Barry has no recollection of him.
>The Flashpoint timeline will exist for a large portion of season 3, but not all of it, although traces of its changes will impact the original timeline once Barry restores it.
>The main villain of season 3 is Doctor Alchemy, voiced by Tobin Bell. A mysterious new speedster played by Todd Lasance will also have a pivotal role.
>Felicity Smoak (Emily Bett Rickards) will make an appearance in episode 2 of season 3.
>Captain Cold (Wentworth Miller) is expected to make appearances, advancing the formation of the Rogues. Gorilla Grodd will also return.
