What a random slaying...I've seen a lot of villains randomly offing partners and henchfolks, but that one stands out. I'm not sure why - it's a pretty typical example of the trope - Pissy Villain's pissy, HenchPartner tells him to chill, he offs them in a rage - but something about this one just feels MORE random.
Maybe it's Man-Ape's annoyance about the mess, I dunno...
