So in V, Aogami's immediate need to protect the MC is a massive unexplained plot hole right?
>Aogami has memory loss and can only remember to protect the protagonist
>believes he's programmed with it
>quickly changes to saying it's his personal vow he came up with
>but he was never programmed to protect the protag
>all he had was memory loss which Bethel fixed

So that means he vowed to protect the protag at some point before the events of the game and never forgot it. When did this happen? Why was this never explained?
