Lydia got "lost" from me last night and when I found her in Dragonsreach, she said that I already had someone with me (I had nobody with me) and would not join, btu she attacked me and chased me all over the city!! I finally did anothe quest with another guy where I joined The Companions. I guess maybe he was counted as "with me" since I had told him to meet me at the site.
Anyway, I wish I would have had a screen shot of Lydia once she finally rejoined me. We were recovering the helm(?) for the Greybeards and she had so many arrows stuck in her, she looked like a pin cushion.

One of the baddies got a headshot on her and she had an arrow sticking out of her right eye socket, it was too funny to see her keep on fighting like it was merely a flesh wound.
