Ohhh.. Maybe Matt notices Foggy's absence, goes out looking, suspecting Mike. Maybe that's how it happens? Their epic tussle?

(I was thinking maybe Matt thought it was a Stick related thing at first, and then he thinks it's not? Or doesn't care if it is? So he maybe goes out looking? Maybe does some parkour? Doesn't know about Josie's, so it takes a while? Here he'd been thinking it was serious, but instead they're out for drinks without him? *shrugs*)
