5 war potentials and now this soul kings limbs thing? Could it be connected somehow?

Right hand Left hand Right foot Left foot

Soul kings eyes where open yet he never said or did anything even whe he got diced up so the fifth could be something like Mind (?) as he seems to lack that too.

Crackpot theory- the reason the soul king awoke when Ichigo was at the SCP was because he contains the Mind of the soul king somehow.
