Hrm. I think I've found a bit of a thin spot in my plot... Basically, it's sort of important that the MC doesn't know this guy who's bossing him around is actually 5 years younger than him. In the introduction to this character he's described as "young-looking" but then a lot of emphasis is thrown on how that's probably not real (fantasy, ya know? Just assumes he's immortal so probably at least 50 years old already, fair enough assumption for a guy in a huge amount of power). Aaanyway, just glancing through the opening to make sure I haven't shot myself in the foot anywhere. At one point the younger man calls the older one "Young [name]" -- a reference to the fact he has a father who had the same name, though also, obviously, giving the impression of being a lot older than him. This is UNINTENTIONAL as a side-effect though, from the younger guy's point of view. He really did just have the guy's father on his mind. As a reader, would seeing someone call someone else "young [name]" make it too unbelievable when it's revealed the true age difference? I can't even work in the named-for-the-father thing until after, since the precocious brat is named for his too, which can only come out after his age is revealed as part of the confusion. There's a whole page between it, in which some readers (I would) might go back to re-read the introduction of this character. Just wondering if it will seem like a plot hole, or over-kill, once the reveal is made.
