Weeeeeell, that's a mystery even to his friends~! I just know he's a famous knight and he's reaaaal strong!

He and I wrestled dozens and dozens of times and we're near even split in wins! Course, that's just immature bonding, riiiight? All friends do that kinda stuff just to pass the time, after all.

[Hinting that he assumed Merlin was a young man who arm-wrestled with his friends and took jabs for fun already proved Ban was not only off, but much drunker than he looked.]
