Did the incident at camp (S4E02) influence Brendon's decision to direct the school play (S4E03), and did failing fuel his character progression for S4?
I've watched this show since 2001 and I never noticed the sequence of events until recently. Knowing that Season 4 shows us Brendon's arc of slowly caring less about making movies and instead focusing more on other things about them, or rather things having nothing to do with movies, from episode 1 with the reviewing getting in the way of his filmmaking, to The Wizard's Baker being a sort of climax to the whole show on some level in his breakdown, and of course the grand finale with the conclusion he comes to about their movies and the end of this era in his life.
Anyway, all of this is say, I feel like Brendon's confidence being gutted from being part of Rabbit Troop, and being downplayed by the campgoers and counselers, made him feel like he had something to prove which is why the next episode is him directing the school play. The idea is, Brendon wants to show them he does have what it takes! Only for the play to be a disaster which sort of echoes that there was truth to what Camp Campingston Falls teachers were saying even with their severe underqualifications. The end of Bye Bye Greasy makes it feel like Brendon went through a bit of an arc to where he is now both aware of a. his general amateur-ish nature, and b. his own lack of interest starting to form towards filmmaking.
Probably overthinking it but that's what you get when you have over 20 years to watch the same 52 excellent episodes again and again.
