Frisk gasped in fear, how was this possible? Both Sans and Papyrus were with Alphys (and apparently Undyne as well), Edge and Stretch were on some kind of honeymoon couples trip in a Hotland hotel, Red and Blueberry were, well... doing whatever Red and Blueberry do, and Ink! And Error were taking care of Paper jam (who was now 5 years old). Frisk just didn't understand, there were no other skeletons allowed in the Classics territory without singular permission, well, the only exceptions were the Fell's and Swaps who had to stay with the Classics due to pests, when the pests were taken care of, both promised that they would go back home (though Frisk was pretty sure that even though it got annoying, the Classics would soon become fond of the constant feeling of love in a pack).

As for Ink! And Error, they were only allowed access to the Classics territory when they needed help with Paper jam. Apparently, Stretch was great with kids, and so was Sans, surprising everyone, even Toriel, they must've just needed a little extra push to regain their paternal instincts that they had when their brothers were just baby bones.

Frisk sighed in confusion, why would anyone want to trespass in the Classics territory? They hadn't done anything wrong, and there was plenty of food, wild and cooked. Though, there had been reports of the Mafiatale Au running out of certain supplies, did that include food? If so, why would they hunt down the Classics food? Hunt down at all? According to the book, skeletons hadn't had to hunt in millions of years, so why would one do so now? And, more importantly... how had Sans or Papyrus not sensed it?

Frisk had learned by personal experience that skeletons were VERY territorial, attacking ANYTHING that they felt got too close to something that they owned. Frisk had accidentally stumbled into Sans' territory outpost, angry about something that monster kid had said and wanting to be able to calm down. Before they knew it, Sans had pounced on them and pinned them down. Getting into position to deliver a killing blow, Frisk had noticed how Sans' eyes had turned into slits, and how he was foaming at the mouth. Luckily, before Sans could deliver the blow, Toriel had raced over to the outpost, sensing something was wrong and knocked Sans off of Frisk, roaring at him before getting a roar in return.

Toriel snorted, picking Frisk up by the back of their shirt with her mouth, confusing Frisk, though Sans only snorted, as if intimidated by Toriel's confidence in protecting Frisk. Sans growled and turned, beginning to pace before completely calming down. "Just make sure they don't come here again, I can't have my post poisoned with the smell of a weak child" Sans spat coldly before walking off on all fours. Frisk whimpered, in shock of how easily Sans was willing to kill them in consent. Toriel growled and walked off as well. After that, when they got home, both Sans and Frisk got a huge scolding.

Sans for almost killing Frisk in cold blood, and Frisk for wandering beyond the skeletal border. After that day, nobody was allowed to talk about the incident (considering the fact that everyone in the underground had heard about it), but that didn't stop people from thinking of it. Even Blueberry had started spraying around the house, afraid of how safe everyone else was, because after that day, Sans was as territorial as a skeleton could get. Alphys had predicted that this was because of all of the testosterone levels in the house, driving Sans to feel like he was losing his territorial dominance.

Whether it was that, or Sans was just becoming more wary of the other incoming packs, Toriel made sure to keep everyone (especially Flowey) on the Skeleton's good side. According to Alphys, a skeleton couldn't get too angry, or else they would become more and more dangerous, and their LV could become very high, very fast.

Looking back to the present, Frisk examined the bite and claw marks on the deer. 'Should I tell mom?' Frisk thought, if they told Toriel, she would immediately blame either the Fell's or Sans, and knowing how much stress everyone was under, Frisk knew that they would have a huge problem on their hands if Toriel did that.

Was there a logical explanation to this? Was it the Fell's? Was it Sans? Is there a trespassing Au pack in the Classics territory? So many questions and no answers! Oh why did this have to happen to Frisk?
