User blog:Agent Minnesota/Yellow Church: A theory

This is my theory about Yellow Church.

One of the Churches from the Terminal decided to possess Caboose, and then attempt to convince one of the Reds or Blues to defuse the bomb. However, when he gets there he is hampered by, ironically, one of the other Churches, the one who mentions that he explained the situation, and "Oddly enough, Caboose was the only one who got it at first". Then, the bomb went off, but Church was sent into the future inside Caboose's mind.

Now stuck inside Cabooses head due to his lack of physical vessels to possess, he decides to blend in by 'usurping' the role of Caboose's memories of Grif. He paints himself yellow as this is the colour Caboose perceives Grif to be, and waits for an opportunity to leave. However, when Sister shows up, Caboose fixes his perception of Grif and Church is forced to become the memories of Sister, complete with a backstory Church ripped off of a TV show.

By the time Regular Church shows up in Episode 100, Yellow Church has fallen into a depression that he has 'forgotten' most of what has happened. When he is thrust out of Caboose's head by Regular Church, and consequently back in time by the malfunctioning Wyoming armour, the familiar sight of a large group of Churches in Sidewinder is enough for him to regain his memory, and such try a new method.
