@MrDidact Sorry I disappeared for a while. Damn college. :/
Anyway, I'm giving the first Tully IC post a bit of a rewrite. The gist of it is that, instead of just taking some papers and leaving Septon Donnel to die in the monastery, Catelyn instead extorts him into leaving with her and pretending he's just willingly cooperating, in exchange for the antidote to the (false) poison. In that sense, the knights that intercept her and her retinue are actually demanding that she hand the septon over. :P
I have the day off tomorrow, so if you're up for it we can get to work on our collab. ^^
