Find my character and observe one of two things:

a) Given that my character's mind was me behind the scenes all this time, she is sitting there like a mindless doll waiting to be taken over. In that case I pull an Ascian trick and take her over and live as her from that point onward.

b) Since her possession by me has now ended, she has her full faculties and mind. First, I beg for her forgiveness as it would be never my intent to take over someone willingly. Provided she forgives me and doesn't kill me on the spot, we sit and drink tea while discussing the illusionary concept of free will and the limits of our perception. In the end, I pledge my support to her and beg her to take me as her apprentice on anything she might want to teach me. We end up falling in love and roam the lands together helping people in need and kicking villains in the butt, happily ever after.
