King Gator chasing Carface at the end... no, better still, his entireBig Damn Heroes moment counts. It starts out with him coming out of nowhere (naturally) and then not only does he free Charlie from being drowned but he also tears a hole through the ship! Sure, the ship wasn't exactly in top notch condition to begin with, but still.
Charlie putting Anne-Marie's life above his own, considering what he knew? Now that's courage.
