Out in the fields where Teren has brought Nick and the others to get their own Evil Spirits, he came back.
Teren has multitudes of Spirits but he only uses some of it to be an all-rounder. But since he had his way of getting Evil Spirits, he might as well get something advantageous. Even since his encounter with Lina, he had been thinking of using another strong weapon in subduing women.
He didn't think if it's ethical or not, he's thinking about how it will work. Having a conscience right now would only be a stupid thing. If it benefits him, Teren will resort to any methods.
Of course, even that is limited if he sticks to reality. After all, he was still clinging onto that one emotion that he hopes will help him recall his lost emotions. As of now, it's becoming a success. Therefore, he firmly believed that he should cling to it until the very end.
