Church is sent "back in time" to this earlier Bungie game
Was created from the Halo video game.
Its in the same universe but not cannon
Epsiode 15 contains Church joking he has no wings because no one "rung a bell".
"Damn dirty apes" referenced in episode 44
The line "I'm scared Dave, will I dream? Daisy....Daisy..."
In Episode 28.5, Caboose/O'Malley says the famous line "And I would have gotten away with it too, if it wasn't for you meddling kids"
A captive woman questions the truthfulness of her rescuer's identity, claiming he's "too short" to be who he says he is. (Sort of like "too short to be a stormtrooper" from SW.)
The "communication melody" from CEotTK is played in one episode.
see quote "Church, women are like Voltron. The more you can hook up, the better it gets" (by Tucker)
"Will I dream?" quote from Sheila echoes HAL from "2010"
In episode 28, in Lopez's HUD, where it has the "Prime Objectives" and the "SAP", it is a reference to Robocop, through his vision it would come up "Prime Directives".
Grif/Simmons bodyswap is a reference to the Rimmer/Lister bodyswap, including the care the other took of each others bodies
In season 3, Church goes back in time to Blood Gulch to save Captain Flowers from a massive heartattack that would kill him before battle with a type of medicine. Which is exactly like when Future Trunks goes back in Dragonball Z to save Goku from a heartattack that would kill him before he fought the Androids.
Donut's spy routine references this film
discussion of "going on three, or three then go"
Gollum/Sméagol scenes are referenced when Doc's personality starts to split with O'Malleys
"I could make a reference to Red vs. Blue with the name Donuts."
When Emerald and Mercury return to the White Fang hideout, Emerald refers to Tukson as a rat. Mercury corrects her and calls him a cat, causing Emerald to question if he was like a puma. This is a reference to the second episode of Red vs. Blue, when the Reds obtain a Warthog and Grif says it looks like a puma. Furthermore, when Mercury and Emerald walk into Tukson's Book Trade, Tukson can be heard humming Red vs. Blue's theme, Blood Gulch Blues.
