枯寂

枯 = 古 + 木 : Karl Koala (ku) is exploring a cloister (古) which appeared in front of the space station (Ø1). In the cloister he finds a Christmas tree (木), but it is stone old (古) and already extremely dried up (枯).

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).
