禍首

祸 = 呙 + 礻 : Helga Horse (hu) tries on her new monk's cowl (礻) in the observatory's bathroom (o4), but she soon realizes a disaster (祸): in her monk's cowl, her breasts look lopsided (呙).

首 = 䒑 + 自 : In the outhouse, the chief lends his piece pipe to Sherlock Holmes. Sherlock smokes some weed in the pipe and looks at himself in a hand mirror, thinking that he's uber cool and that he'd pass as a quite formidable chief himself.
