People are starting to believe zangetsu/ywach is just ywach trying to fool ichigo but i doubt zangetsu wanted to mislead ichigo, he acted like a real mentor and when he became tensa zangetsu he acted like a brother trying to protect ichigo. Perhaps zangetsu being ywach is just a representation of ichigo's quincy powers since he is a descendant from ywach and ywach is in every quincy spiritually speaking.
