I don't agree with Andy, she new what would happen to her brother yet she is mad her boyfriend saved him and she also has more trust on the other guy instead of her boyfriend
The other guy has been her moral support since day one. He's seen Andy's boyfriends come and go, but he has always been there, supporting her and guiding her in all of her decision, thats why she trust him more than any man.... Frankly a lot of viewers thought he should have been end game ( her bf likes to play too many games and he acts like a player ).
