Canon Defilement: Mrs. Lockheart denies killing her husband in her debut in the story, claiming that the bear killed him. However, she remains just as guilty for instructing the bear to kill him in the first place.
It's not until "Little Maddie Lost" that the story gets really good, as it is the first chapter to have Meg and Zack's daughter Maddie talk.
"Jillian the Genius" marked the end of the mediocre chapters following the fanmail.
Hilarious in Hindsight: Apparently, some of the writers for the canon series looked up this fanfic and emulated parts of it.
The cutaway for Peter's funeral in "JOLO" wouldn't be out of place in this fanfic.
The second-to-last chapter of "Family" has Peter pose as a female wrestler to get revenge on Raven's mother Olga a.k.a. The Iron Maiden after she beats him at arm-wrestling. "Peter's Sister" would have used a similar plot a few years later.
Meg encounters an evil clone of herself at least twice in this fanfic series. Then she eventually would for real in a throwaway gag in "A House Full of Peters"—albeit with less pleasant results.
Brian dating another sentient dog in "She's a Mad Dog" would eventually become a reality in Season 16.
Les Yay: Olivia is pretty much in love with Maddie.
They Wasted a Perfectly Good Plot: Meg and Zack's wedding. Before Meg's Boyfriend shifted to episodic adventures, it spent time on their relationship and the time they spend together, up to and including taking care of Meg during her pregnancy. With how well these two have been getting along and the things they went through, one would think Malcolm Fox would have added a wedding chapter to the schedule. Instead, their wedding was glossed over with Zack saying "Oh, right. We got married yesterday in Vegas. I keep forgetting." This is an odd and unintentionally jerk-ish thing to hear from basically Meg's Mr. Perfect—and at their child's birth, no less.
Unintentionally Sympathetic: "Cody's Mom" shows that Maddie is in the wrong for being quite jealous of Cody after Nikki abandoned him on a freezing winter day. Yes, calling him a "bastard" was uncalled for, but Maddie was being ignored by Meg, who rebuked her for being jealous at one point.
