McReary Siblings' Friends
- At the end of the comic, the siblings are all woozy when they come back from San Salvador's party. After they fall to the floor, Ma asks them "Did you guys mistake the fruit punch for something else again?". They may have accidentally drank liquor.
- It is unknown how they drank liquor, because being underage, San Salvador should not have that at his party. It is also mentioned later on that he does not drink and does not have any liquor at his parties.
- Joel was grounded in "Gonzales Vs. McReary", so it is unknown how he was able to appear in this comic (which is mostly set at San Salvador's house).
- Also, it is strange that James Johnson did not appear with Joel.
- Mark Sanders breaks up with Kate in this comic, but it is not shown, and their breakup was not mentioned until "Happy New Year!".
