Quite a few people including myself though Hussie might take advantage of the retcon to fix one of the few actual plot holes in Homestuck: WV's "travel to a session" machine is set to go to the "next" one instead of the "previous". The famous Frog Switch. However, when Bec Noir shows up, the switch has flipped offscreen, despite only WQ having the key and WV being locked inside his capsule the whole time since she showed up.

Anyway, John's oil could have covered the switch so there was no (visible) plot hole, or his hands could have moved it or something. Maybe it could even be plot relevant that there was something that didn't quite make sense.

In the end, it was obviously deemed too irrelevant to even address.
