I found that really interesting. I sort of walked away from Star Wars thinking 'gee that was cool', but reading this clicked in a lot of ways.
Revealing Ren's face was, I think at least, a very deliberate choice. When you combine it with the temper tantrums he throws and the discussions between Leia and Han - he's their child. He's a person. Darth Vader's lack of reveal until the very end of 6 was great, but this can be different, that's ok.
