Sub-Episodes
Sub-episodes are backup features in the Sonichu comics that relate tales of Christian's adventures during his Love Quest. Nobody knows why he calls them sub-episodes. Chris stated in the videobooks for Episode 12 Part 1 that he stopped making sub-episodes because his mom made him.
Typically each sub-episode is inspired by some actual event in Christian's life that left him so utterly traumatized that he felt the need to express himself and tell his side of the story in comic form. Sub-episodes are primarily Chris's way of seeking external validation: By presenting these stories he hopes someone will read them and pity (and therefore love) him. For this reason the stories always assert Christian's rightousness while dwelling his pain and suffering.
The first four sub-episodes first appear in Sonichu #0-3. It could be argued that the Sonichu stories in these comics are nothing more than a Trojan horse scheme to get people to read the sub-episodes, so they can learn what a special snowflake Christian is. Sonichu #4 is dedicated entirely to sub-episodes, re-presenting the first four and introducing four more, with Sonichu himself reduced to cameo appearances. This could be interpreted as Christian finding response to the initial sub-episodes insufficient, and trying to hammer his points home with a full-fledged all-Christian issue. On the other hand, by Sonichu #5 the sub-episodes are obsolete since Chris believes he has found a sweetheart, so it is also possible #4 was intended to clear out a backlog of these stories.
A common theme in many sub-episodes is Christian loitering in a store somehwere until super-powered security guards demand that he leave the premises. Chris then uses his own super powers to fight back, and he is generally defeated, necessitating the arrival of one of his characters to save him. After his foes are vanquished so that they cannot make him leave, Chris delivers a speech and leaves anyway. Even in his fantasy world, Chris manages to Fail.
