- This comic marks the first appearance of Salvador Real, who would later star as the protagonist in Sibling Rivalries: Salvador Real's Adventures. While Salvador was polite in SR: SRA, he was depicted in this comic as being very sarastic and rude. In later comics, Salvador was shown to be more dim-witted.
- Strangely, the McReary family don't remember Salvador from SR: SRA, since in that comic, they interacted with him in a scene. However, their encounter was very short, so it would be possible for them to easily forget Salvador in the 21 months that passed. It may also be a retcon, since GTA Nerd did not begin working on SR: SRA until nearly two months after this comic.
- Retcon: In the haunted house, Kate falls in love when she sees her boyfriend Mark Sanders, but Kate reveals in Happy New Year! she and Mark broke up in San Salvador's Story.
- This is the first comic of the series that Joel Gonzales did not appear or was mentioned at all. In fact, he is absent throughout most of the season; he only appeared in the season finale "Dodgeball Mishap", although he was mentioned in "Happy New Year!".
- The author of the series explained the reason for Joel's absence for most of the season was due to him getting grounded for two months in the Season 1 comic "Gonzales Vs. McReary" (which would be set between October 20 and October 31, 2013). Joel, however, still appeared in the rest of the Season 1 comics even after his grounding (except "Diamonds in the Rough"), but he only appeared once in Season 2. He started to make more appearances in the series following his un-grounding after "Dodgeball Mishap".
