Who will return for Season 2?
Raising Dion wouldn't be Raising Dion without the titular character and his mother, so it's reasonable to expect Ja'Siah Young to return as Dion and Alisha Wainwright as Nicole. Given that Dion's father, Mark, still technically isn't dead, we'll probably be seeing more of Michael B. Jordan on-screen. Count Jazmyn Simon's Kat in for Season 2 as well.
The jury's still out on Pat (played by Jason Ritter), who was defeated in the season finale after managing to hide his identity for nine episodes. After his defeat, however, we saw the storm-like entity possess Brayden, another second-gen super like Dion. Given that cliffhanger, we'll definitely be seeing more of Griffin Faulkner as Brayden. Ritter's appearance, however, is more up in the air.
The rest of the supporting cast is a bit of a toss up, but we'll probably see Sammi Haney and Gavin Munn return as Dion's friends Esperanza and Jonathan, respectively. Given that scientific organization BIONA is still around, Ali Ahn will likely return as Suzanne Wu, the organization's head.
