Rewatched "Revelations" on DVD.
The "creatures/beast" theme: Mace Malone describes Goliath as "a majestic beast". (The evidence, though, indicates that he recognizes Goliath as a sentient being rather than a mere "beast".)
This time around, when I saw Mace Malone's fate, I found myself thinking of the depiction of his ex-partner Dominic Dracon in the "Religion 101" radio play, searching everywhere for those diamonds in a way that indicated that he'd suffered a severe mental shock at the end of "The Silver Falcon". Though I recognize that the radio play isn't canon, I'd felt that it did seem like a probable consequence for DD, after discovering that those diamonds had never been in the Silver Falcon - and Mace Malone's own fate, frantically trying every door, convinced each time that this was the one which would get him out of the Hotel Cabal and to freedom, felt like a parallel to it.
I like that observation.
