Did Emily really like/Love Brendan
I never got a sense she really cared for Brendan like he did for her, always felt from what we seen that Emily saw Brendan as a pain in the ass she wanted rid off as she didn't want to be reminded. That's why I love the film in a way Brendan goes through all this danger and risk of his own life for a EX, who probably wouldn't have shed a tear for him if he died. That's why the ending is sort of more bleak then many think, I buy Laura when she says Emily probably wanted rid of the baby as she didn't love her ex.
That's why the ending is a gut punch, sure Brendan got the bad guys but is left knowing his ex was carrying his child but wanted rid of it cause she didn't love him.
