The fact that Eric was born probably means he let Ellie go. And the way Ellie came back doesn't seem like he made a decision yet. I think Pain told him to leave to make Brutal heirless ( ̄∇ ̄")
Oh no, when brutal told pain that you owe me, he was probably refering to his daughter! Ellie being pains art, brutal resented him and is trying to get revenge!
Oh my gosh!!!! Pain heard!!!! Please be a good guy!!!! Help them escape!!!!
