One character gets killed by a block slamming out of the wall and into the side of their head... Popping it right off. And it's not a perfectly smooth edge, like it was cut in one smooth action, and it's not ragged, like it was torn, but it's flat except where the spine is, and it looks like it juts out an inch, where it's cut flat again. Pretty much exactly like how some mannequin heads are, if they're locked in place with an external screw.
