First, they must rescue Chompsky from some blood goblins.

- When confronting the Trollhunters regarding his missing staff after Usurna's visit, Vendal states "I've put my neck out far enough for you ungrateful fools. Any further and she'll be sure to lop my head right off." This could be a potential foreshadowing of Vendel's death at the hands of Usurna.
- Title: It is an obvious shout-out to the 2005 mystery/crime movie, Kiss Kiss Bang Bang.
- Continuity: When Jim takes his bag off of the baluster, the baluster begins to fall off of its foundation, as AAARRRGGHH!!! nearly tore it off when he clambered upstairs to avoid Barbara Lake in "Becoming: Part 2".
