Original Commentary
This conversation just keeps going from worse to even worse for Patrick, doesn't it. Not that he hasn't brought most of it upon himself. Although his point is very valid, the fact that everyone knows each other is simply coincidental... but I doubt Sandra cares either way at this point. -Isabel

Modern Commentary
Dude keeps hooking up with his sister's friends. He's not doing a great job convincing Sofia that she's not just another notch on the proverbial bedpost here.

He's doing so badly that Sofia isn't going to mention that he just called her brother an annoyance. There's more immediate issues here - Terrence
