It's not very late yet, but this is still my bed time. I've scripted and penciled pages 16 and 17. Gonna try doing a bunch of scripting/penciling now, because I think the writing will get harder to do the later it gets. Inking and even drawing I can do on autopilot, if not well. Writing requires conscious thought. I need to form the words.
Poured a glass of Diet Coke. Hopefully the caffeine will help.
Also, if I have the pages ready for drawing and inking, I think it'll be easier to resist the temptation to crash.
