If Shalash switches orders, will there need to be a new Herald of light weavers. If so that would help to explain Shallan and how she seems to not know who she really is. There is obviously way more to Shallan and how she gets lost in her many personas'. She says in OB that Vale and Shallan are equally false, also when fighting Re-Shaphir she seems to have partial memories possibly from Shalash whe she bound her the 1st time. And it could explain why she was able to have bonded pattern and get shard blade as a child before she spoke any oaths that we were aware of. Just thinking out loud probably wrong never can know with Brandon, but man do I love it!!
