[Awww, does the best bird want some headscritches and dried seaweed, she's such a good girl. Because of course Muffet brought dried seaweed in case Hresvelgr was there, that's just how she works.]

[When Ardyn arrives, she straightens up and offers him the bowl with a polite smile.]

Hello, I'm given to understand that it's tradition to bring food over when someone moves into your neighborhood- or back into it, in this case. This is for you, assuming you don't mind potatoes.

[Knowing Ardyn, it's probably not the potatoes he's going to have an objection to so much as the sentiment behind it, but it seems politer to phrase it this way.]
