awesome! basically max was adopted by two women around the age of 11, he was more or less a trouble maker and deemed the "bad seed" before this but they adopted him anyway. i had said that they adopted his sister a few years after max but i'm fine with switching it to before if you'd prefer! her age is and everything is completely up to you, max is 25 himself! all i really had him mention about his sister before is that she's a big animal lover just like he is but everything else is down to play with really. i'd love it if they had a close relationship, sort of understanding each other from the perspective of being given up by your parents and everything, just someone who would have been there for max when things got bumpy and vice versa for her too.
