Jo's section went very smoothly. I had no trouble picturing her as a teenager.
Sarah took a little bit of work, nudging the conversation where it was supposed to go to keep the action parallel.
Ace is...not cooperating (how unexpected of her). I'm struggling with the voice since this is the first time I've written her as something other that "this is Ace, she blows stuff up". I need her to be more complex in this, since she's carrying a third of the story. I may have to watch some of her episodes this weekend to see if that helps.
I think I'm going to close out the file, and see if it moves more smoothly in the morning.
