It may be a little late for me to give this reminder, bloonewb, but if you feel like none of what happened in my last IC post would prompt Morgraine to do anything aside from following Dietrich, just say the word and I will presume as much and throw out another post assuming that she continues to follow in silence.
Also, as a reminder and recommendation not only to you, but to all players (in fact I'll go check whether it is mentioned in the OP and add it there if it isn't (update: checked, and I actually have the recommendation there, too)), I think it would be advisable to either have a post dedicated to having up-to-date information about your characters or updating your CS as changes occur. I do this for all of my NPCs, too; for instance, Victor's CS originally contained points reading:
Clothes: Wears the garb of the white church.
Hunter gear: Wields a Ludwig's Holy Blade and a Hunter's blunderbuss, and carries a hand lantern on his person.
Whereas now, those points read:
Clothes: Wears the garb of the white church. A 7.6 centimeter (3 inches) hole has been cut through the front and back of the garb, each hole surrounded by a large, dark bloodstain. The right shoulder has a long, blood-soaked tear.
Hunter gear: Wields a Ludwig's Holy Blade and a Hunter's blunderbuss, and used to carry a hand lantern on his person. The lantern has since been destroyed.
Currently has four blood vial and thirteen quicksilver bullets.
I'm mentioning it not only because some of the characters (Nigel, Arcturus and Ludolf, specifically) earlier received a blood vial each and that it would probably be beneficial for the players to have a way to remind themselves of as much, but especially since Morgraine is currently in an ideal position to get herself a significant amount of supplies,
and have changed clothes. I keep my own notes on not only my NPCs and your characters and what they have on them, but it would probably be useful for you to have that information as well.
(Morgraine is also still unarmed, just for the sake of mentioning it.)
