Sorry, but it's Anuriel (the Steward) who's the girlfriend of Unmid Snow-Shod :(

Here's their dialogue (from UESP's CS, which contains all of the dialogue in the game):

Riften Keep Scene 08
Unmid: Anuriel, would you please stop declaring that the city is safe for the Jarl to roam? You and I both know that isn't true.

Anuriel: I would never knowingly place Laila in danger, you know that too. Why do you always question my judgment? You don't trust me.

Unmid: I trust you, I'm just concerned about her safety. That's all. Don't be angry with me.

Anuriel: I'm not angry with you. Tell you what, lover. Meet me in my chambers later and we can discuss the situation in private.


Riften Keep Scene 07
Anuriel: Unmid, my sweet. Are we still meeting later for... combat training?

Unmid: Of course. Your training isn't complete yet.

Anuriel: I look forward to it then.


Wylandriah and Unmid don't actually have any dialogue. Wylandriah only talks to you and to Jarl Laila.

Still, there's no reason for this to affect your prompt :)
