What happened to the Reptilian imposter of Lee Harvey Oswald? Was he able to return to his full Reptilian state, or did he have to eventually “die” as Oswald?

This imposter was able to return to his Reptilian state. He was not a true imposter in the full sense of being able to step into the role of Oswald. He was a semblance in having a physical duplication but was given instructions on where to go, what to do, how to act, and what to say, and so never attempted to fit into Oswald's role in a way that would be undetectable. He himself left Dallas following the assassination and was still in his Oswald guise because he would pass as human and used the means of a military plane belonging to the intelligence community to make his exit. This story is known as he was seen in the company of another conspirator boarding a plane that landed in Dallas and was there waiting for that purpose. The real Oswald was truly a patsy as he claimed, and this was not the Reptilian who was subsequently killed. He was an innocent victim himself of the conspiracy to kill President Kennedy.
