Is that guy your guide or are you always sneaking up on people and attacking them from behind?
yes, you follow a guy for a while until you get the tutorial parts done, then you can go on your own or hire a mercenary to go with you. Also, the one guy I wanted to get his elbow that I just bashed the hell out of with my war hammer and he was like "hey, watch it." I'm like "nag, I just freaked yo crap up and that's all you say!?"
