When I went back in I discovered to my horror that the last scene I'd written had head-hopping. Oh, the horror, oh the humanity! I start with my secondary heroine's POV, jump to my secondary hero's POV, back to my heroine's, then ended up with my hero's, and I'm a POV purist. I was mortified. So I rewrote that, wrote a few more pages and then sat and brainstormed for a couple of hours.
So five new pages, rewrote a bunch of old pages, and then planned.
