As I'm sure most if not all of you know, Lewyn was killed at the Trident along with Rhaegar of course. If you go back and watch that scene from Season 4 where Oberyn talks about Elia, Rhaegar, and Lyanna, you can definitely detect his resentment to the last two. I can't help wondering if Lewyn felt the same way but kept his oath and fought alongside Rhaegar anyway. It would be really interesting if he somehow knew Rhaegar had another child with Lyanna.

They only have seven hours to work with in Season 7. I dont know how much time they could devote to side character that doesn't impact the story. Rhaegar and Lyanna are vital to the story, seeing as their kid is basically Game of Thrones Jesus.
