So Greg this is a confusion that I have regarding time travel on Earth-16. So when
asked Neutron status post Bart's time travel you previously said "Because of his close-proximity exposure to Chronoton radiation, he will have to teach himself what happened. He will never truly experience the revised timeline as memories. In theory."
And on twitter you said No when asked about whether Neutron from season 2 and 3 will in 2056 have his new memory supplanted by Neutron of the old timeline.
So my question is that in 2056 will there be two neutrons, If the Neutron from the old timeline gets added to this new timeline and exists alongside this timelines native Neutron then why did the old timeline Neutron's appearance change. It's just I having a tough time understanding rules of Earth-16 time travel can you please help explain this.
