Chapter 1: Pain
Sans had adapted to the resets long ago, conducting himself as the human dictated. Whether it was a peaceful or genocidal run, he had it down to a science. It had been a long time since he had been surprised. To say that this situation was shocking was an understatement, at the least. While it should have been a breath of fresh air, the small skeleton wasn't in any position to enjoy it. His sockets closed against the harsh light as a soft sound of pain rumbled in his broken rib cage. Gloved hands….human hands….cut his jacket away from the wound slashed across his broken bones. The presence of so many humans was alarming. Sans tried to process what they were saying, but there was too much pain. Why wasn't he dust by now? The trauma that Chara had dealt had usually been enough to force him into a retreat, with just enough magic to be able to teleport safely to Grillby's to wait for a reset. But a reset never came. Instead, there was a terrible sensation of falling and the smell of the void as the monster was thrown to stars knows where. This is obviously another timeline, but why was he on the other side of the barrier? Why was he still injured? Why was he still alive? He made another quiet noise as the hands began splinting his ribs. The burning agony caused his consciousness to fade into sweet darkness. Sans lost time between these lapses as he struggled to remain awake, finally settling into the darkness of sleep.
