Me thinks that the 4 most important people in Emma and Henry’s life were shown. Regina– being Henry’s mom in SB, Snow and Charming–Emma and Henry’s family, and Hook– Emma’s TRUE LOVE)
Well in fairness Neal IS important to Henry’s life. I think it was more to do with who was important to Emma’s life – since she’s looking in her rearview mirror.
I think it was necessary to have Regina in that shot because she was stopping her curse… but her back is turned. She’s not relevant to the shot. But the rest – the Charming’s and Killian, 3 of the most important people in Emma’s life – they are turned towards her and she can see their faces one last time.
