I have a Staff of Zombies(Let's you resurrect dead things to fight with you) that I'm intending to sell, but I have to wait until my local vendor has more money. I start to leave for the Greybeards place, when I realize I'm still carrying it, as I'm too lazy to turn around and put it in my house, I hand it over to Lydia and forget about it.
Continuing on the path we encounter a dead elk, and farther up from the Elk I stumble upon a Flame Atronach, who I proceed to do battle with. I beat her down with my Orcish axe and wonder where Lydia was during this battle, she has a legendary ice sword that would've cut the battle time in half. A second later she comes running up, in her wake is an Elk.
Not sure why an Elk is following her I swing at it and kill it, only to realize that she had resurrected it with the Staff of Zombies.
I wasn't expecting the AI to be capable of using any and all weapons you give it.
