True it is just a teeny reminder but still, Gray was gunning to defeat Natsu since childhood. I'm sure he would have been told or at least discovered that he couldn't eat his own flames. Not really a problem but still would've been a nice effect to have a flashback in their childhood days. Actually Natsu did look a bit derpy so maybe he expected Gray to have known or Gray was just confirming since he never bothered to before. Just me over-analyzing the thing really.
