Writing on a strict deadline is actually really damn hard. Especially when you have to consider all the realities of budget (can we even afford that scene?), availability (oh, these two characters that should interact in that episode just.. can't. Huh.) and producers meddling in your writing (I gotta change my big plot twist because the producers didn't like it what the fuck that was the entire fucking point of that fucking story aaaaaaaaaaaargh).
