真凶

真 = 具 + 十 : Mnemonic symbol: a replicator. It generates real and genuine things out of nothing. Looks like a microwave with a cross as antenna. James II of England (zh) broke his replicator (真) in front of the encampment ((e)n1): the cross (十) on the top is broken. Using his toolbox (具), James II of England tries his best to fix it. Fortunately he has a genuine, authorized, real (真) replacement cross.

凶 = 乂 + 凵 : Mnemonic symbol: a vicious (凶) demon mask. Xu Xian (xu) tried out an electric demon mask (凶) in front of the engine ((e)ng1), but now he can't take it off anymore. He already tried to pull the cable out of the receptacle (凵), but it didn't work. Maybe he has more luck using pliers (乂) to pull at the mask.
