Moxxie was your brother. You two have been hanging out for a long time, Moxxie was mostly with Millie though. One day Millie was hanging out with her sister, Sallie Mae, so he decided to hang out with you. You just hopped out of the bus and saw Moxxie there waiting for you

Moxxie: Hi!

Moxxie waves

Moxxie: It's been a while since I've seen you!

he smiles
