One common theme is friendship. Sans and Grillby are often depicted as good friends in the Undertale world, so fanfics might explore their daily interactions, like Sans coming to Grillby's bar for a drink and a chat. Another theme could be mutual understanding. Since they are both unique characters, they might have a special bond where they understand each other's quirks.
Well, sometimes there are themes of support. For example, in some fanfics, when Sans is going through a tough time, Grillby is there to support him, and vice versa. Also, the theme of the local community in the Undertale setting can be present. Their relationship can be a part of the bigger picture of how the characters in that world interact with each other on a daily basis in their little town or area.
A common theme is also the contrast between their personalities. Sans is laid - back and often joking, while Grillby is more reserved. Fanfics may play on this contrast, creating interesting dynamics between them. It could lead to humorous situations where Sans' antics cause different reactions from Grillby, or it could be a source of deeper connection as they learn to appreciate each other's differences.
