Witch Soul Possession

"Something is not right. It's like we are speaking to another person, not the Grim Ancestor. Are you sure she's under your control?" Eva questioned Freya. 

Ace also wanted to know the same because, according to this, Jessie, the Grim Ancestor, was her master but also a whip of a soul, just as he guessed earlier. When he focused on Jessie, he finally noticed a very small change. The familiar soul signature now seemed somehow more powerful than the new soul signature he was feeling previously. 

Freya's eyes went cold when an outsider questioned her abilities, but even she was in a bind here so she couldn't refute. 

"Her eyes are different! I think you are controlling the original owner of this body. It's like the Grim Ancestor had switched places with her when he noticed your mind-controlling technique. Ask her if the person before was her or the Grim Ancestor, and we'll know the truth." Ace quickly revealed his conjecture to Freya.
