Baruk
The paladin disguised as a thug raises an eyebrow at the sight of the unicorn, but says nothing. He does his best attempt at a sluggish, brutish posture; it comes naturally after a moment of recollection. You can put a half-orc in shining armor and teach him Elven, give him nice clothes and a pretty moral code, but in the end, he's still a half-orc.
