 * The title of the episode, "Bloodletting", refers to Carl losing blood at a rapid rate and the future of the group hingering on whether or not he survives.
 * Rick and Carl share the same blood type (A Positive), which is a very common type, found in about one person in every three.[1][2] The circumstances strongly imply that Shane's blood type is something else, and likely not O Positive either, since the possibility of having Shane as a secondary donor is not even raised. It is reasonable to assume that Shane and Rick are well aware of each other's blood type, since they worked together in police duty often before the undead apocalypse. The fact that no one else at the farmhouse is used to donate blood to Carl suggests that they are also incompatible.
 * The crystal meth found in Merle's stash of drugs is the same color as the meth produced by Walter White in the AMC TV Series, "Breaking Bad", which has spurred a few fan theories that the Breaking Bad and Walking Dead universe is the same, and that Jesse Pinkman was Merle's dealer.
 * A support to this is that in Season 4, Daryl mentions that a "scrawny white guy who said 'i'm gonna kill you bitch'" was giving the meth to Merle.
 * T-Dog's real name is revealed to be "Theodore Douglas".
 * This episode features one of the few instances where the world before the apocalypse is shown, with the others being "Days Gone Bye", "After" and "Wrath".
