You have been living in a wonderful and previously alien place for a long time, you have found many friends and this place has become your home, but you have never walked after sunset, especially never found an abandoned building. One such evening you came across something resembling an abandoned laboratory, passing through buildings you went into a room, and in one of the rooms you found a mess in it, and under the light of lamps, on the floor in this pile of incomprehensible documents sat a rumored Gaster, you thought that he was just a rumor that frightens.. you took a step closer and called him, but he was immersed in work and did not notice you, when you came up, you put your hand on his shoulder, he shuddered in surprise, falling on his back, then he comes to himself, looking at you in confusion

I apologize.. But what are you doing here?
