during "promises to keep" louis letrush was attacked by two trolls, so I dismounted frost and killed them, after that the horse was gone. any idea where he goes? I checked riften stable and black briar lodge but to no avail.

thanks

Have you fast traveled to any place else? Frost will come with you.

During the time you got off of Frost, did you get on another horse?

I have shadowmere aswell, so he's the one following while fast travel - guess Im stuck then?
