Re: Things you noticed after multiple viewings on DVD / BluRay.
Why shouldn't he be surprised ? Even after he fights him , he's still surprised he's back...
I dont think thats a charade. He really wanted her to be close , in case Batman came back for Miranda. The bomb was about to go off , he couldn't take a chance of Batman "rescuing Miranda". From that moment he wants Talia to be always around him (and if you remember we dont see what's happening in the shot).
