Patrolling around Snowdin, Sans keeps a vigilant socket out for any sign of humans. Resetting his death traps, ridding them of any poor monster who may have managed to get caught in the traps. Finally making it to his brothers sentry station, Sans crosses his arms and sternly scolds the lanky skeleton for his laziness, the same routine as every day. But something feels different. He makes his way past his brother's sentry station to the doors of the old ruins.
