07/17/12 - First of all, congratulations! Aela is quite the catch! Remember to ask her to Train you for free.... Secondly, she likes to hang around at the Companions main building -- the Jorrvaskr in Whiterun -- so if you "lose" her, you're likely to find her there (or close by -- check the forge, etc). Wait a day or more if she doesn't turn up. Thirdly, she may have gone to YOUR house, assuming you've completed the Thane tasks (see p405 of the guide). For Whiterun, you're looking for the Breezehome (just down the road from the marketplace area). It's worth finishing the Thane task for Whiterun so you can purchase and furnish this house, store your loot there, and find that wandering wife of yours!
