How long it will take Regina and Daphne to forgive Angelo is certainly up in the air, but it will happen. It has to. Now that Angelo knows that Regina never cheated on him, he is determined to stay and be a part of his daughters' lives. He will succeed, because there is plenty of story to be had if he does, but almost none if they turn him away. To keep a drama going, story needs to be there. Expect Angelo to be around Switched at Birth quite a bit in season two.
A sweet subplot of "The Homecoming" involves Toby (Lucas Grabeel) and Wilke (Austin Butler) trying to convince Emmett to play a gig with their band. When Toby realizes Emmett is breaking Bay's heart, he stops caring about the gig and talks seriously about his sister. But the best part of the whole situation is how quickly Toby and Wilke begin treating Emmett like they would any other guy. An obstacle portrayed in the show is the hearing community's strange behavior towards the deaf, something Emmett is well acquainted with. And of course, when the boys first meet Emmett, they are guilty of the same. But only weeks later, while perhaps taking slight advantage of the hook of a deaf drummer to land the gig, they are communicating perfectly normal towards Emmett. Lesson learned?
Switched at Birth has been renewed for a second season, and will return soon (probably winter) to ABC Family.
