Faelivrin, I would be very sad to see you leave this project. I think that you have brought a great deal of insight to this. I hope that I can help mitigate some of the fears you are demonstrating. Firstly, Galadriel does not know that Earwen is there until she makes her leap. So she does not think Feanor is trying to kill her mother. From her perspective, it seems as though Feanor is trying only to escape. She certainly does not try to kill her own mother. While she has distrusted and disliked Feanor, she has still decided to accompany him, intending to travel with him all the way to Middle Earth. Believe me, there have been decisions that Prof. Olsen & Co. have made that I wasn't thrilled with in the past. This one stems from a desire to give Galadriel agency she does not have in the Published Silmarillion. The way it is written implies heavily that she was with Finarfin and did not participate at all. I'd be ok with that. Just a reminder, though. At no point do I suggest she actually slaughter the Teleri, nor even attempt to do so. She is actively attempting to stop the Teleri from killing the Noldor that are aboard the ships, and then trying to stop them from killing the Noldor to the right and left of her. When she sees Earwen, she immediately ceases all hostilities and tries to save her.
