I know this has been discussed before, but I'm having trouble finding the exact thread/s. So if you happen to know them, feel free to send me there!
I just wanted to say that it sure seems like Tien was a future Lightweaver in process. There's lots of things to point us to that, I know, but this is my favorite one that I haven't seen brought up (but it may have been):
"'See,' Tien said from behind, "from this side it's green. I don't think it's a spren, Mother. It's the light. It makes the rock change....."
Doesn't that sound like a future Lightweaver point of view, y'all?
Or of course this could have just been an overarching Stormlight Archive theme getting brought up. Honor was He Who Transforms after all. I know I'm reaching on this one. Either way, I really love this line.
