No part of the trailer implicates that there will be any Robin in BvS. It only suggests that the Joker already killed Jason Todd. It would be very cool if Nightwing was featured, though. Also, Tim Drake as Robin; because that would be the right Robin to do, not Carrie Kelly. I don't understand why people are so sure that Jena Malone will be Carrie Kelly; I think it's more likely (and would be way cooler) that she'll be Barbara Gordon. Batgirl deserves to be done right in a movie, don't you all think? Also, Batman's solo movie should introduce Damian Wayne.
