no surprise you throw the blame on Killian! thats Emma, THEIR daughter's TL boyfriend.
the scene at the loft when Snow talk to Emma about her secret and about the life she is trying to build with Killian, thats the kind of conversation she should have with her daughter.
noticing Emma is not okay, and instead of going to ask her whats wrong, let her know she can tell her whatever is going on, she goes and have a peep talk with Regina, because poor Gina, she has such a difficult life. forget her daughter's life was ruined because of that other woman and her revenge.
but sure its all about Killian Jones
