I was key to Corey’s decision?What was conveyed to the Execs was that there was a conflict between the timing of the Galadriel storyline and their initial request to have the Kinslaying reveal come before the Dagor Aglareb.
Here on the boards, most people* liked the idea of moving the Kinslaying reveal later to address this conflict.
Clearly, the Hosts preferred to alter the timing of the Galadriel storyline to accommodate the earlier Kinslaying reveal.
Corey Olsen does often have to be reminded of what he'd said earlier, but once he is reminded, he remembers that. He did not forget about the Galadriel storyline, he was simply looking for ways to condense it and have it happen earlier to preserve the mid-season Kinslaying reveal that he wanted.
The significant alteration of Galadriel's storyline is that her conversation with Celeborn at the Mereth Aderthad where she discusses the death of her mother is now being combined with the conversation where she reveals the kinslaying to him. To accommodate this, we will likely find an opportunity/excuse for Celeborn and Galadriel to meet and speak prior to the Mereth Aderthad, either by bringing her back to Mithrim or bringing him back to Doriath. We do need to iron that non-trivial change out, but...we can work with this.
Something had to give - we either had to alter Galadriel's timeline or alter the Kinslaying reveal timeline. I gave them the Gantt chart with the kinslaying reveal at the later slot; they were well aware of our recommended alteration. They just chose not to use it. That happens.
