孤寂

孤 = 孑 + 瓜 : Gitta Giraffe (gu) is currently the space station's lone (孤) inhabitant. To feel less lonely (孤), she drew a mosquito's (孑) face on a melon (瓜) to have somebody to talk to in front of the space station (Ø1).

寂 = 叔 + 宀 : Joan of Arc (ji) has a philosophy doctoral viva with her uncle (叔) Arthur Schopenhauer (叔) in the space station's bathroom (Ø4), but she remains completely silent (寂) for the whole time. Arthur Schopenhauer is impressed by her nihilistic performance and hands her her well-earned graduation cap (宀).
