the heartbreaking thing about Andrew and Aaron is that if they had met either earlier or later in life their relationship would probably be a lot better. if they met as adults, more healed, more settled, without tilda in the way, they likely would’ve been much more open to each other and maybe even have a bond that resembles normal brothers much quicker.
but that couldn’t have happened.
because if they hadn’t met when the did, there wouldn’t be a ‘time when they’re older’.
they both would have likely died if they hadn’t met when they did - Aaron would get consumed by Tilda and the drugs and Andrew wouldn’t have anything to live for
their meeting saved their life - and doomed their relationship.
