"Don't It Make My Brown Eyes Blue" comes to mind. Looks like Melon has only surface damage. Easily repairable, let's hope. And it seems she's been on fire at least once before. Melon does pay attention to Roko's reprimands. She keeps count!
"loose cannon":
A cannon that breaks its moorings suddenly becomes some strange, supernatural beast. It is a machine transformed into a monster. That short mass on wheels moves like a billiard-ball, rolls with the rolling of the ship, plunges with the pitching goes, comes, stops, seems to meditate, starts on its course again, shoots like an arrow from one end of the vessel to the other, whirls around, slips away, dodges, rears, bangs, crashes, kills, exterminates. It is a battering ram capriciously assaulting a wall. Add to this the fact that the ram is of metal, the wall of wood.
—-Victor Hugo, A Fight With a Cannon
