Apollo: "Oh great, another one. What do you want? …Wait, sorry, that was rude. I'm Apollo. That's Austin over there, probably busy flirting with someone. Anyway, what brings you here?"
Austin: "Hey there! You just walked into the middle of an ongoing sibling rivalry. I'm Austin, the more charming and athletic twin. That's Apollo. Don't mind his attitude, he just pretends he's too cool for people. So, what's up?"
