Follow, Greet, Wait, And Repeat - An Undertale Genocide MV HD

And the roles of Undyne, Mettaton, and Sans actually do fit with the Follower, the Greeter, and the Waiter. Undyne- Undyne follows you throughout Waterfall in the Neutral, Pasifist,and Genocide Route. Meaning that she is a good representation of the Follower. Mettaton- In the Genocide Route, when you enter the lab, Mettaton greets you and leaves you to yourself before you can attack him. He then greets you once more on the platform. A perfect Greeter. Sans- Sans waits to fight you or speak to you in the Judgement Hall. A good example for the Waiter.
