"I-i-is this real?" Bruce stopped being sure of what he did... He didn't know what was a hallucination, what was a nightmare or what he actually committed... Haunting him, he was constantly staring, examining needing you.  "I-is there blood in my face?..is it mine? Do I have something in my hand?.. Did I kill? Did I hurt you?"

Maybe Bruce did, maybe he didn't.  Maybe he's not actually seeing anything real or he snapped back to his senses.
