The thing that has always most impressed me about your shows is the meticulous planning that goes into them early on. The little, seemingly innocuous threads that you drop only to pick up seasons later (eg. The kids on the bus in Young Justice).

My question is, what is the biggest event (released to date, no spoilers 🙂) across any of your shows that was completely spontaneous, and not planned out from the beginning? Or else something that had to be changed drastically at the last minute from the original plan?
