Reworked the Main Character Throughline for 2015-02. Managed to get her out of her own head and more focused on the Activities troubling her (As it should be with a Main Character in Physics/Activities). Difficult at first reworking scenes that I thought were working, but now they're charged with greater purpose. A prop that used to be in the scene just because, now is in there to bring out my Main Character's personal issue.
Still running into a snag during the 3rd Signpost (second half of the traditional 2nd Act), but I think I might have figured it out on the ride home.
