* SugarWiki/AwesomeMusic: 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.
* 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.
* ThisIsYourPremiseOnDrugs:
-->'''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.
