I heard Danny was coming back a while ago... Besides the last we saw of him was the end of season 3b when Ethan was leaving and he told Ethan that he knew he was a werewolf! I want Danny to come back!

Colton (Jackson) won't be back because he's pretty much a main character on Arrow.

Daniel (Isaac) may come back because there wasn't really much of an explanation for him leaving in the first place.

I doubt they're bringing back Charlie Carver for Ethan just because both him and Max (Aiden) may (as in they might) be in the next season of The Leftovers.

Adelaide (Cora) probably won't be coming back either because she's THE main character in Reign so...

Anyone who died is pretty much a given to not come back. At least not for anything major. They might just be there for a flashback or something.
