警械

警 = 敬 + 言 : Joan of Arc keeps on toasting to herself inside of the engine and she got so drunk that someone called the police. The police warns her with a megaphone that she's going to be arrested if she doesn't stop, but Joan of Arc just toasts them and drinks the next shot.

械 = 戒 + 木 : Marie Curie (xi) finds a turning machine (机械) under a Christmas tree (木) in the elevator's bathroom (e4). Happily she proceeds to manufacture a ring (戒) for herself.
