My theory is that the Lone Wanderer and the Sole Survivor are the same person.
I don't need my own evidence though, I'm sure @CT Phipps could make up an excuse for me. Please?
The Lone Wanderer was kidnapped by the Institute and false memories implanted in his brain taken from the braindead but well-preserved body of the Sole Survivor. Elder Maxson recognized the Lone Wanderer and believed he was suffering amnesia or choosing to hide his identity, hence his rapid promotion through the ranks. Ultimately, the Sole Survivor was shocked out of his delusion by Shaun's death.
