User blog comment:Eobard95/Is Vigilante the real Adrian Chase - Still portrayed by Josh Segarra?/@comment-24152851-20170712110258

This was actually the original-original idea I had before other theories replaced it. It'd be like Prometheus pulling a Jay Garrick. Adrian's real name being revealed to be Simon Morrison does support the theory there's a "real" Adrian Chase out there.

But if we go with the twin theory, that raises a whole set of new questions. Where did the name Adrian Chase come from? How are there no records of the twins even when Simon Morrison was there? Is it a coincidence that both twins happened to be masked psychos operating in Star City or is there more to it than that?
