yes, I saw this morning that Mama Colton will show up. not sure we'll get to see the entire Colton family, though. Javicia Leslie is still in NY filming for "God friended me" I think.
So I guess Riley is part of the Billy and Mama Colton storyline while Ethan seems to be part of the storyline involving Mac, MacDaddy and Desi; maybe also Bozer and Matty.
So... which one is the "Hearbreak" and who's the "Treason" in the episode title? I think both Billy and Ethan could be both either the heartbreak or the treason
