 * Why didn't the architect just take the caretaker's body earlier?
 * Note that Kroagnon's speech becomes more and more lucid as the story progresses, starting out with vague statements such as "Hungry!" and becoming fully capable of conversation just before he takes the Chief Caretaker's body. Presumably his mind needed time to gain in strength (possibly somehow making use of the corpses taken by the cleaners) before it could be transplanted into the Chief Caretaker.


 * The caretaker's moustache doubles in size after being posessed by Kroagnon
 * Perhaps this is a side-effect''


 * How do the Rezzies that Mel meets get their door repaired every time Pex kicks it down? It seems unlikely the Caretakers would replace a door so easily, since it's already replaced by the second time Mel comes back to their flat.
