I've notice a lot of hate for the guy among everyone who's played the game, which understandable of course. He ripped Jodie away from the only loving family she's known(Nathan and Cole) so it's a little weird that she can fall in love with him at the end.
I was a fan of him at first but i kind of warmed up to him by the end. Looking back i think Ryan was just a CIA puppet, like Jodie, but except he didn't want to believe it.
Also, whatever you thought about the writing of the character, i thought the acting was good enough to make me like him.
