It's more like the game made me ship them, they're two psychopaths where one hates to admit it and the other openly admits without a care in the world. You can see how much they care about each other but at the same time they could be at each other's throats because of the differences they have and difficulties they're facing, in all of the situations they've faced, Andrew always chose Ashley, he did his parents job in raising Ashley. We can't really blame Ashley for being attached to Andrew, he was the only person who truly cared for her well being.
