The Ruby impostor had a very cleanly razored neck with a high horizontal hairline and a beveled sideburn. The real Ruby had a scruffy neck, showing that he was 2 or 3 weeks out from his last haircut, and a regular sideburn. It means that they cannot possibly be the same man. And the very fact that they brandished a Ruby impostor in the garage tells you that the real Ruby wasn't there. Because: if the real Ruby was there, they wouldn't need an impostor.
Now, this is final. There is no talking point around it. If you are an adult, if you a mature thinker, this settles it. But, if you continue to ignore it or fight it, then it means that you are a corrupt thinker who is biased by your own leanings, and you have no regard whatsoever for the truth. This is the litmus test of your integrity.
