Once again, Gray uses his brain to get around his opponent's abilities. Honestly, Gray's fights may be short but it's always nice to see a fight that isn't won because of a random power up.
Gray vs Racer-Gray noticed the range problem with Racer's magic and won
Gray vs Sugar Boy-Gray destroyed the key but memorized it's exact structure and thus made a new key.
Gray vs Ultear-Freezing his own blood to get past Ultear's time magic.
Though, as much as I liked this fight. I have to say, I didn't understand the build up to it. Yes, yes, I know....Sabertooth is a bunch of pricks and Rufus did hurt Gray during the first day....but here's what I don't get. Gray acts like Rufus murdered his parents or something, all Rufus did to Gray personally was attack him during the first day, and he wasn't just aiming for Gray....he managed to hit multiple characters. If anything, that little spikey douche from Raven Tail should be on Gray's hitlist...but he's locked up and I guess Gray just feels like he should get back at Rufus for the humiliation of the first day, plus Rufus was one of the guys that enjoyed the show of Minerva beating Lucy to near death. It's just....Gray makes this fight look so personal but yet Rufus hardly even acknowledged Gray at all before this fight. That's just my opinion, still a great chapter regardless.
