My point is that "Listen" is an oddity among stories in which multiple incarnations of the Doctor appear, because there is no clear evidence in the story itself that the boy is the young First Doctor. He's only confirmed to be the Doctor by implication, unlike all other such stories which outright state that multiple Doctors are playing a part.
