I pretty much agree with all of this. I was disappointed in the lack of any building on Darwin and Carrie's relationship, and "The Ghouls' " lack of literally any mention of it (aside from Darwin being aware that she doesn't like Halloween, I guess?) was downright infuriating, and kind of soured my opinion of the episode overall, despite my initial excitement. As for Penny, the only reason I wasn't complaining about her absence was because her recent roles had been so "eh" for me (other than that bit in "The Petals"), and I found "The Pact" so funny anyway. With Rob, it'd take a lot of resources and strenuous effort to match his previous roles, so I can understand why they turned him into a purely comedic character, but it would still be great to have them at least address the past, and "The Ex" just felt like a surprisingly lackluster way to rekindle his loathing of Gumball.

Overall, even if it doesn't always bother me massively, the lack of proper endings for arcs can get annoying, much as I love the show, especially right now.
