So I guess this is going to be my theory: After losing Robin, Regina ponders going evil again because she finds that heroism doesn't guarantee a happy ending, so why not? Henry gets mad, runs away, but after they find him and talk,  Henry realizes that destroying magic is not a good and  Regina decides that her relationship with her son/the rest of the squad is more important, so she forgoes going evil. However, after Regina and Henry encounter "Jacob" (Jekyll/Hyde) in SB, he will slip her the potion and surprise - she goes evil anyway! -cliffhanger going into season 6-
