There is a chain of thought that say The Pretender actually was Edward but was forced into confessions that he was not to saves other members of the family. He was apparently identified by his sister
The very fact that he was not executed strengthens this chain as Henry Tudor was not really a forgiving man

I personally do not think the princes were killed in the tower I believe Richard died of sicknesses he had ( documented illnesses) and Edward freed
