In your Lucky Clover AU, would Starlo join the Royal Guard because; A, it would give some validity to his sheriff claim and; B, so that he could get word and try to deflect any investigations for the missing human that the Royal Guard launch.

This was such an interesting ask I really had to sit with it for a while. Huge ramble ahead!

So, this idea fascinated me solely because this is a little bit of what the situation is with Martlet in this AU. After Clover decided to live in the underground post Pacifist ending, she put in her two weeks and quit, since she does NOT want to risk being ordered to kill or hunt down Clover, or any other humans for that matter.

It's something she struggles with a lot; not only because she's jobless for a while and probably has to ask for financial assistance from Dalv/Ceroba/Starlo, but also because she KNOWS being in the Royal Guard would give the gang some insider intel on the missing human investigations. Maybe it would've been better to tough it out in a job she wasn't content with just to get that info, to protect Clover? While her friends reassure her that this was the best decision, for her and for Clover's safety, it's something Martlet struggles with for a while, especially considering how some Snowdin Monsters side eye for her suddenly leaving her post and job.

Now, for Starlo. If the situation called for it, would Starlo try and join the Royal Guard? Perhaps if there was no other option! He's the kind of person to go above and beyond for the people he cares about, sometimes to reckless degree. However, I think his relationship with the Royal Guard is far too sour for him to ever be considered for a job with them, based on this line from Ceroba.

Dude literally has made a habit out of locking Royal Guards in his town's jail. Undyne is NOT accepting him into her ranks LOL. (I honestly HC that although Undyne and Starlo have a lot in common and some similarities, they probably would hate each other if they met or were forced to engage in conversation with one another LOL).

As it stands in the AU, none of our main cast has any connections to the Royal Guard, as much as they would like having some kind of way of getting side info, in order to protect Clover. Martlet is in a weird spot with her old co workers, and Starlo's pre-Pacifist ending habits and way of running his town had pretty much killed any chance of that. The best they can do is just keep their eyes and ears peeled in order to ensure no Royal Guard ever discovers Clover secretly living in the Underground.
