警戒線

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.

戒 = 戈 + 廾 : Joan of Arc (ji) asked to see the holy ring (戒) in the elevator's bathroom (e4). She is allowed to see it, but she has to wear handcuffs (廾) as precaution. Additionally, there is a guard equipped with a spear (戈) standing next to the ring.

线 = 戋 + 纟 : Mnemonic symbol: barbed wire.

线 = 戋 + 纟 : The silk worm wants to use the floating tank in the anthill's bathroom, but there's already Marie Curie inside—and she secured the tank by setting up barbed wire all around it.
