* CrowningMusicOfAwesome: The Mexican Standoff- tension, confusion and paranoia reach their climax as a pained gargle and the first notes of Dimmu Borgir's Puritania signal everyone to drop what they're doing and [[BackToBackBadasses Back to Back Badass]] their way out of an enclosed gladiatorial arena filled with Wall Crawling zombies. This scene also probably has the highest concentration of CMOA's in the whole series.
* FridgeLogic: At one point Mullins [[spoiler: falls off and cliff and survives.]] He then monologues completely straightly that it's "not like the worst day of his life". Okay... So... WHAT THE HELL WAS THE WORST DAY OF HIS LIFE?! How bad could it have been compared to being in a GeniusLoci[=/=]EldritchLocation?
* GrowingTheBeard: The first episode had no story and poor animation. The second episode had better quality animation, but still not much of a story. Then, Castle 3 burst in with even better animation, a story, and a fully voiced cast. ''Castle: Repercussions'' upped the ante even more.
* MemeticMutation: Some Other Guy is practically this in the community forums.
-->'''Mullins''': "WHAT DRUGS ARE YOU ON, BOOMER?"
* TooCoolToLive: Lloyd. Possibly.
* [[WhatDoYouMeanItsNotForKids What Do You Mean, It's Not For Kids?]]: Aww, look, it's a cute little stick figure cartoon- OH GOD OH GOD SO MUCH BLOOD MAKE IT STOP.
