The thing about Ultimate Showdowns of Ultimate destiny, or even smaller "character from fandom A vs character from fandom B" battles, is that you have to decide which universe's rules are going to apply. And this doesn't just apply to things like what sort of magic or phlebotinum works. For instance, being Lawful Good is a lot less fatal on the Discworld than in Westeros (as long as you stay away from the Lawful Stupid side of things), even allowing for the series' drastically different body counts.

Fille du Regiment was fun, and it was great to see horitsu_kami again, but every time Marie started singing about how she was born on the battlefield or some such thing I kept having MGS flashbacks.
I also now have a couple of pet mice. This should be an interesting experience, because I've had hamsters, gerbils, and guinea pigs before, and my mom's kept rats, but mice are new to us. They're so tiny that in a weird way it's kind of intimidating. I don't want to accidentally squash them.
