The Natsu vs Gray fight has been set up since the Tartaros arc so I don't understand why you're surprised about that. It has been foreshadowed that gray will have a huge role against End if he does turn out to be evil or whatever(Keyword "IF" so don't respond to me talking about "there is no End and Natsu won't turn evil" or That "End is a separate being and Natsu will end up turning evil" or what because I'm sick and tired of these debates and discussions about End) and considering how his magic is effective against demons he will obviously deal some major damage. During his little match with his dead teacher he was trying to restore Lyons resolve and convince him that the Ur in front of them wasn't the real deal. Once they got serious, they ended up one shotting her which I'll admit doesn't really count for much since it wasn't the real her and since everybody else pretty much did the same thing with the historia's they were fighting.
