So is this Iskander (Alexander the Great) re-incarnated into the modern world. Iskander was in search of immortality and here we have a recruited kid named after Alexander the Great who drinks ambrosia and is now "immortal" whatever that means (unclear if at this point it is cannot die unless killed, eternal regeneration, or cannot die period etc.). Even if this is unintentional it is a nice little nod to it.
