As a random side note, Seth doesn't get Axes. FE8 Paladins had Sword/Lances only, it was Generals and Great Knights that got the full triangle.
Not sure it largely matters as Hand Axes aren't the most accurate of things and Sothe's got at least some evade and...yeah.
Also, regarding the villain spoilers thing?
Lekain is one of the more prominent villains, really. Clearly the main antagonist for most of the game. Now, granted, not worth spoiler tagging him since he's pretty clearly against you rather early on (heck, its obvious something is up with him after his first scene with Sanaki in Part 1), and there's no MYSTARY!!! aspect to it, though some plot related to him is a bit spoilery, albeit, not something that'd come up in a topic like this. Either way, not a character worth tagging, really.
