Huh? Has she got quieter since you added Neeshka? That's something I have never seen!
Maybe you have been sneaking more - then she is quieter...Thank you for sharing the pictures!

Lol, oh, no she does not. I don't mind her repeating her little quips while we're walking around -- they add atmosphere and I find myself replying to her out loud, even if it's something I've already heard her say.

The only bit about that, that really bothers me is that she's constantly commenting on my complete ineptitude at sneaking, even when I'm over 75 sneak and can run without making noise. I kinda liked these back when I was first starting out, as she would remind me to slow down so as to not be detected, but I thought it'd go away as I reached a higher level.
Vilja, "You're making more noise than a guard patrol!"
Me, "But I'm an Expert!

"
It's amazing how well people take care of her - she must seem rather real, as they bother to consider her as something else than an extra shield.
She's a much better follower than any of the followers I've seen, even in Fallout. And that's due to largely to her great amount of dialogue. When I was choosing a companion before I started playing, I noticed how much dialogue Vilja had and that it was all voiced. I was originally considering getting a second follower, but I couldn't find one that really compared to her, so I stuck with just Vilja.
Though, if there are any supported pet mods, I wouldn't mind a wolf or dog or something. I'm sure Vilja wouldn't mind either. She's brought it up more than once.
I know you said that the Cheydinhal Pet Store one doesn't work because it affects global timers or something.
I also like hearing her thoughts about our quests.
In Fallout 3, I could take a quest and Clover would just say, "I'm bored."
Or Star Paladin Cross would say something like, "You do your father honor." or something completely irrelevant.

I buy the Strawberries, Sweetcakes, and Sweetrolls out of every store I see them in, too

Well, most people I can find to voiceact would have a swedish accent, and *that* would be odd on these various npcs. As it is only a little topic that is not voiced I think it's probably still better to keep it like that rather than having them change accent. The side-characters in Vilja's story are all fully voiced (Heneri, Runar and all the rest of them).
Ah! I haven't met these people yet. It took me the longest time to find the Shy Root of Hunger. I'm already level 20 from doing all the other side quests in the towns while going around checking the Mage Guilds' alchemy shops.

I'm on the next ingredient, I think. Going to Cheydinhal next to meet the mean Dunmer's mama.
