Actually, Angelo left after Daphne got sick. He found out he wasn't her father after he got a DNA test. In the beginning of episode 9 in season 1 Daphne has a dream about that. If the switch hadn't been made, Daphne would have never caught a virus. And Bay would have grown up deaf like Daphne and she would have been dating Emmet. Case Closed. And they made a whole episode about both girls growing up with the Kennishes. That's season 2 episode 15.
