I am off to the 7,000 person monster local SF convention. I have a panel on alternative history at 11 this morning and one on how to write villains at 7 tonight. My final panel is at 11 am on Sunday: how to write heroes.
I actually don't have an opinion on how to write heroes or villains. I write them the way I write all characters: one sentence at a time.
I skipped the second panel and came home.
