I think the Musketeers might have a penchant for huffing magical gunpowder or something, they seem a little bit delirious!
Also, the whole execution idea of someone dying "the wrong way" makes me think a bit of Ocelot in Metal Gear Solid 3; the Musketeer gets so caught up in trying to be really stylish and fancy, adhering to "The Plan" that they make amateur, clumsy mistakes and get frustrated over it. They want to send a bunch of bats hurtling down a bottomless pit at the end of the rooms all at once so they toss a bomb at the group to propel them into the hole, but overshoot the bomb and end up sending a horde of now-flightless bats waddling around on the ground and biting at their feet. Pretty great! XD
