The constant outsmarting, tense flirting, and who's better at the chase while they probably don't even realize it. God I loved the whole scene and chemistry. I'm still pissed that she lead him to Bane's trap even if she didn't know that he was Bruce, but I'm glad she learned from her mistake and knew she couldn't leave him again. It was the turning point for her character.
Batman want her to lead him to Bane---so she did fulfill their agreement
outcome 1, if Batman defeat Bane---Selina may feels good
outcome 2, if Bane defeat Batman---Selina may feels ok(she was starting to feel awful when she learns Batman actually is Bruce )
