So I don't have any option to tell my companions "This is your new home," (I remember a few years ago I had a companion mod that allowed me to do that) and when I do have them wait inside one of my houses they either stand there, draw a blade, and swing at the air or immediately undress any clothing they have equipped and run into bed and sleep until I wake them. Are there any companion mods that are a little bit more.. realistic? I mean in terms of having a companion realize that I'm giving them free roam of my house, to use my chairs or read books or eat and drink, not just stand there naked swinging a sword in a corner of a room? I'd like it to work with random companions - I don't want to download a specific companion mod that has a script just for that said companion.

I'm currently using CM Partners Mod V2

The obvious answer is Emma's "Companion Vilja", who has an amazing number of functions, including home and sleep. When in "relax" mode she'll do stuff like make potions, read, eat and drink, and sometimes sweep. There are a few home mods dedicated to her which give her even more functionality.

I once used Companion Neeshka, who also has a home recognition function. She's not nearly as sophisticated as Vilja, but nice none the less.

Neither is part of the CM Partners system.

Blah, that's too bad. I checked those mods out, and they were great, but I wanted something that I could use for Battlehorn Castle. It's empty as hell, except for the dozen or so naked or semi naked followers rooted in place swinging daggers and swords at shadows.

I think there are a number of mods that expand and populate Battlehorn castle. Check the Nexus.
