怯弱

怯 = 去 + 忄 : The Queen of Hearts (qi) is quite timid (怯) and does not dare to use the elevator's bathroom (e4) with her personal protection: a flail (忄) and a concrete barrel (去) which she uses as body armor.

弱 = 冫 + 弓 : Rachel Rhinoceros (ru) created a piece of art in the observatory's bathroom (o4). She joined many composite bows (弓) by sticking their ends into popsicles (冫) which weren frozen again afterwards. Her whole construction is a huge armchair, but it is very fragile and weak (弱), so Rachel puts on it many of these "handle with care" stickers.
