The Maze Runner - The Scorch Trials (Spoiler 2):

Worst way of almost dying > Winston:

The metal starts melting. It is hot (VERY hot) and sticky. It covers the victim's face burning it. It keeps on expanding all over the victim's head until it covers all of it. When the victim's head is 100% covered, it dries like a perfect sphere. When that sphere is fully dried, it starts killing your head, cuting it from the inside until it separates from your neck.

Winston survives t at this, but all his head was burnt. His head was FULL of blisters.

DISGUSTING

(anyway, he dies 9 chapters after that one)
