Heh.
Some Nord woman was my sidekick all the way, and I grow fond of her (she was really good with the great sword and staffs and she always got me out of teh tight situations), and before the mission in the Talmar embassy I forgot to tell her to wait for me (thinking: she can't go with me anyway since its a mission for one person and you go there with the carriage), and when the fight started much later around the embassy, suddenly she appeared (she must have been running behind the carriage all the time O.O) and she died since she spawned outside the gates where I can't go to help her (mission is set like that)...
Naturally I rewritten saves before she was alive and well... :[
So, for those that have sidekicks that they like: Tell him/her to wait! Otherwise: you won't even have a grave to put a flowers for them.
Now looking for another lady sidekick. :P Utghard the Unbroken will be missed.
And now she is called Utghard the Broken!
