Archive Panic: SGR ran for seven years, and towards the end there were four comics a week. Adding Bobbins (about a thousand strips) makes over ten years of comics: when you put them all together and add the sporadic Scareodelia comics, you get...a realisation that John Allison is much more productive that you are.
Continuity Lock-Out: Scary Go Round ended in September 2009 because John Allison decided the weight of continuity was putting off too many new readers. He then started another comic, Bad Machinery, and began panicking that the drop-off in web traffic meant he'd shot himself in the foot. Seems to be recovering, though.
Harsher in Hindsight: The beginning of the final chapter (dated June 08, 2009) introduces a character who is a very obvious parody of Michael Jackson. You can already tell how this is going to end, can't you. John Allison later put up a news post explaining that the character's appearance in the storyline had been long planned out, and Jackson's death just happened to be an unfortunate coincidence.
Hilarious in Hindsight: Shelby's comments on "real American heroes," and whether John McCain qualified as one, took on a whole new meaning after Donald Trump made the same argument (apparently in all seriousness) during the run-up to the 2016 U.S. elections.
Moral Event Horizon: Rachel crosses it when she tries to have Shelley killed, and she's definitely gone when she shows no remorse for it.
