I just wanted to share a funny story with you.
I was on a mission for another word of power in one of the ancient ruins. In the last room I had come across a dragon priest and a drauger overlord. After killing the priest, I proceeded to run up the stairs to take care of the overlord, but Aela was in my way. No matter how hard I tried, she would not move and I could not jump over her. I was being shot by arrows from the drauger so I had no choice. I sometimes find that if you slash your followers a couple of times they will move, but I guess I held the button a little too long because the game went into a cut scene power attack and I killed Aela with a sharp stab to the belly. During this some profanity spewed from my mouth and then went up the stairs and killed that pesky overlord. I was a little pissed at myself due to the fact that she was carrying quite a bit of valuable loot that I could sell. I will go back and pick at her corpse after I drop some stuff off.
All I have to say is that the biatch had it coming! She's been annoying me for quite some time.
