We're in This Together

Ships: Killermare, HorrorDust, Drink (Just saying, not gonna be focused on them)
Fgod Error. I assume you know him, right? Well, basically Fate ripped a Sans from an AU, destroying his family in the process, to make him the destroyer. Why? Well, Fate's idiotic child, Ink, is the creator of AUs, though he makes AUs too fast, filling up the multiverse. If there's not enough space AUs will bump into each other and start a painful chain reaction of destruction that can't be stopped once started. So, the destroyer must destroy AUs, or copies, to make sure the Multiverse doesn't get too filled up. That destroyer is known as Error. (Fgod Error belongs to @harrish6, I recommend reading harrish's story if you want to know enough since I'm lazy TwT)
Anyways, Error decides to commit suicide after a brutal beating of the "Judges" and Ink. By jumping into the VOID.
Now, my twist. Say... The Bad Sanses, were waiting in Outertale for Error(Not knowing he was getting beaten) and once they see him jump, they instinctively f o l l o w.
Well?
