Haha Padfoot. (Chapter 10 of TLAT):
- James: Where were you going, just now?
- Sirius: To find you, of course.
- James: That would have been fruitless, as you had absolutely no idea where I was.
- Sirius: Didn't I?
- James: Well, I have the map, so you couldn't have known.
- Sirius: So, does that mean that you weren't speaking with Professor McGonagall outside the staff room?
- James: How did you know that?
- Sirius: I know you. Prongs, we've been mates forever. We've been mates since before either of us knew what a Confundus Curse was... since we were so oblivious that we actually wished Hogwarts wasn't co-ed. We've been through just about every single important life experience together... except birth. I mean, when you were getting your very first detention, who were you taking the blame for? Me. And when I got my very first detention, who was I trying to spring from his very first detention? You. We first heard the White Album together. We worked out how to get into the girls' dormitories together. We convinced Marvin Eggers that he was a girl for an entire day together. I was even in the room for your first kiss, which was awkward, let me tell you, and I am damn pleased Carlotta never found out I was in the closet. Point is, we have hand signals and secret codes for just about anything we might need to say but want concealed... You've always been my best mate, Prongs, and I know you.
- James: But, really, how'd you know?
- Sirius: Ran into Larisa Montanez on my way back from Lathe's... she told me you'd gone to find McGonagall in the staff room.
