Ahem. I love the sort of odd parental relationship between Batman and Nightwing. Even though Nightwing is a lot less dark in terms of personality, he and Batman are more alike than either of them will ever admit. Which is probably why they fight so much. <3
I like Alex Ross's perspective as to whether or not Batman's eyes would be visible through his cowl. As Ross pointed out, Batman would never do anything that would impede his field of view. Plus, showing the eyes allows for a much wider range of expression, and I love Nightwing's baby blues.
Nightwing and Batman belong to DC, blah blah not mine blah.
