I'm going to invert the Shifts structure... instead of hearing from Remus except on full moons, I'm going to have it Tonks's POV, and hear from Remus only around full moons. I mean, I realized that more or less, the interesting stuff that happens to Remus happens on or around the transformations, and it just clicked.
I like when that happens. It's a cool feeling when the lightbulb just goes on.
After much interior hemming and hawing, I'm going to stick with Remus calling her Dora, because that's embedded in this ficverse, even though he does call her "Tonks" twice in HBP. I'll think of some workaround for that.
