I'm normally, the same but after the first flashback to the kid's escape, I turned to my friend and said the kid looked like Tate. It seemed really obvious to me, and I didn't get close to noticing eye colour. My conclusion was wrong though. I assumed the kid was Bane and Tate was his sister.
Speaking of the kid's escape, I realised on second viewing that Nolan told us expressly that it couldn't have been Bane before the conversation between Bruce and the doctor in the Pit. Bane says as much during the first fight - something like "I didn't see the daylight until I was an adult" or something. Also, the doctor talks about performing surgery on Bane after the prisoners beat the shit out of him, and yet when the kid climbs out there's not a mark on her face and no mask.
Lastly, the hulking bodyguard in the first few flashbacks are pretty obviously him in hindsight. If my memory is correct, it's amusing how Nolan lays it all out in plain sight.
ETA to cancel some of the unintended self-importance of my first remark.
