Ah. Ptol10 will still go with the others inside the cavern. Ptolemaeus will still remain outside, but go along the cavern roof. The highest part is 75 feet, so I don't have worries staying out of range of Ror and lose my copies.
As an aside, I will be having limited internet access starting tomorrow until around January 7 as I will be having my holiday vacation. I will try to post when I can, and on occasions when the game needs to progress, please feel free to exercise all liberties with my character.
Sorry for the inconvenience.
EDIT: As a general course of action for Ptol, he and his copy will start off with the Uruk-hai, then the Witchlights.
