I started a female character that I was going to turn into a vampire hunter in preparation for dawnguard. I'm in helgen currently and whenever i press the sprint button I hear female dialogue (that I can only assume is my character?) say things like: "are you prepared to die?" and "I'll kill you if i have to!" She also makes yawning and coughing noises when I press it aswell. I've never experienced this before and I'm wondering what's going on...

lol I want that.
You accidentaly created a bandit, those things she says are what bandits usually say.

Lol, what an awesome glitch!

Sounds like shes mad at you for making her run and become exausted...

Awesome glitch!

I had this when I created my Khajiit he always scremed in pain on every little hit, its sorta stopped now and I don't notice it.

Awesome mode activated now if only we could summon Arngeir through the sprint button too.

One youtube video i watched had dovahkiin freeze arngeir with the freeze shout (ees sleh nooze or whatever) and as a result frozen arngeir went on a jolly ride down the throat of the world thats more fun
