She totally blows my cover every time. She rushes in, gets pummeled, and leaves me hanging. I've even told her to wait many feet back, and as soon as I fire my bow, she runs in.
Is there another follower that actually follows me.
There is a big burly dude named Thonnir from Morthal who is supposed to help you in a cave. If you don't do that mission right away he follows you around. BUT he follows you too closely so he bumps into you all the time, I mean he shoves you out of the way. You might be looking over a shelf of books, picking up item on a table, and he will come plowing into you moving you bodily away from whatever you were looking at.
HE IS THE WORST! All Thonnir does is bump into you and whine, and since he bumps into you so often he often gets hit...which means he starts fighting you or your other companion. About seven times after a battle Thonnir would start fighing me because he got in my way. Meanwhile Lydia would come to my aid and she would alway thrash him til I would use a calming spell on him.
