In the upcoming season; The Flash will have two new series regulars. Cecile, Joe’s Baby-Mama, will be a series regular. Which isn’t a surprise to anyone. But will she still have her mind-reading powers? And will their baby have any meta-powers? I’m sure the show has something in mind for the new family, and we’ll probably find out what that something is next season.
And this isn’t a stretch; Ralph, The Elongated Man, will also be a series regular, probably taking Kid Flash’s spot on Team Flash. Keiynan Lonsdale is taking some time off, so he will be back for a few episodes only. They’ll probably send the character off to college or something. So Ralph will be back in the mix full time. And I think that’s a good thing. They can do weird and fun things with his powers, and he’s a likable character.
