The first taste

The sleepy town of Snowdin has some new arrivals: a little family of skeletons. The father, one doctor Gaster, seems to take a keen interest in Grillby. With how alluring the mysterious newcomer is, is it really any surprise Grillby falls for him hard and fast?

Too bad about the sickness going around though.

And what are these markings Grillby finds on his neck?
