Now that I think about it I don't think there was any PIS here. This is because RF obviously held back and didn't kill bruce when he had the chance. He could have easily done it while he blitzed him on the 47th second mark. All he had to do was continue blitzing instead of asking him if he's still alive.
Batman only got hits in because he was able to stab RF in the feet with a batarang and that is only because Thawne acted like an arrogant prick.
But what I have trouble understanding is how Batman's resourcefulness was downplayed here. In my opinion he should have pulled a contingency out of his a** here. They were literally inside the Batcave. He had enough opportunities to do so but instead he chose to take RF on in h2h. That seems stupider to me than Batman getting a lick on an RF that was playing around.
