Little Daniel getting possessed rather than Big SB Daniel. (Also another mini prediction)

Throughout the webtoon, there's always been the possibility of the 2nd body, big Daniel, getting possessed/used by someone else. From the old James Lee arc, the prescence of UI etc. What if instead of doing the obvious, PTJ decides to make small Daniel gain possession from someone else instead. Perhaps the man we keep seeing in his dreams. After all, this man has only appeared in relevance to small Daniel rather than big SB Daniel.

Also a mini theory/prediction:

Big SB Daniel being the main one brings the focus on the Second Body. More than likely, even though Jinyoung is dead, and more likely because Jinyoung is dead, we will probably find information of the Second Body in the later arcs. Whether it's someone we already know or someone new.
