I was doing some Companion quests and I had Farkas with me. At one point he started sneaking. I wasn't sneaking, but he was pretty determined to sneak. If this wasn't already strange enough, he used sneak roll for everything. Rolled up the stairs, down the stairs, towards enemies, behind enemies and all sorts of crazy stuff. He even managed to do some sort of combo. Sneak rolled behind a draugr and did a kill move into it's back. So I ask you if this kind of sighting is normal?
