So according to my post, your horse is still outside on the streets, or at least was when Kyron was there.
According to plan, Merek will pick up Atina and Kyron by the back door, near the stables, thats why Kyron went to check it. Also, the Inkeeper is a nice guy, likely letting Magnus sleep in the stables for free and maybe even give some food because of how wretched Magnus looks.

I just don't want our posts to like, say different things about things that should be the same. I seem to have messed it up, I'll edit the post when necessary
