Prospero and Moriarty's scheme is actually not to recover the staff but to replace it using wood from the Tree of Knowledge located in the heart of the Library. Baird and Carson are able to reach this location despite problems with the Library's security system and the interference of other fictional characters summoned into existence by Prospero. Carson destroys a tree that Prospero incorrectly believes to be the Tree of Knowledge, and Prospero flees, while Moriarty (under threat of being sent off a cliff by Baird) agrees to withdraw from the dispute. Jenkins confesses that the Library has systemic problems he cannot explain, including several artifacts that have disappeared. Carson leaves alone in search of these, while the reunited Librarians prepare to help Baird with the Library's work.

When Moriarty first appears in the annex by Prospero, he walks past Prospero and goes to slide his finger on the shelf as if to dust it. The actor messes up his initial slide, but pulls it off w.o stumbling at messing up. See more
Excuse me, I'm going to take care of my desperately not wanting to be here.
