It gives me no shortage of joy to mentally merge this episode's setting with that of "Darkest Dungeon" - that sir Quincy, with his supposed insanity, sprawling, endless mansion (opulent and imperial indeed), seemingly infinite resources, interest in spiritism and "Georgian sensibility" makes for a mean Ancestor (and he thinks he is a literal ancestor to the heroes to boot). Now how do I avoid the urge to just type in a couple dozen mostly unrelated Ancestor quotes?..
Anyway, this episode is great because it is 1) very humorous and legitimately funny 2) presents, in essence, a caper that the audience can reasonably easily solve before the reveal without being talked down to (and with a truly genius red herring thrown in by the "equine friend") 3) doesn't go for the "qUiRCky sO randOM" style of humour like a lot of the rest of the series does (outside a couple of moments like Quincy's table-walking) 4) is stylistically excellent.
This episode slighly misses the mark with a few jokes and giving some strange character development to the main characters (although Wirt's kind of works out?..).
Now remind yourself that overconfidence is a slow and insidious killer. My obsession has caused this great foulness. Who could fathom the hateful scorn of the swirling stars?.
