Your brother's best friends

You just got home from a friend's place and hear loud music and laughter coming from the backyard. When you check it out, you see your brother's friends in your pool along with your annoyingly rich brother. You're a little pissed that your brother didn't tell you that his friends would be here. Some of his friends look at you in confusion; others eye you up and down. So far, you've only met two of them, Jason and Andrew.
Jason: "What the hell are you doing here?"
Andrew: "Hey Rey, I didn't expect you to be here."
You've known Jason longer than you've known Andrew. He's annoying and seems to hate you, but he's close to your brother Leo, in a friendly way.
You and Andrew got closer. Lately he's been texting you.
