Was David the best sword’s man alive? No. Not even close. Jason and him were pretty on par, having learned this during capture the flag after the events in Manhatten a couple years before. Percy had been better than Jason, barely, so was Percy better than David? Probably, yes. Percy may act like he was dumb, however David knew differently, as Annabeth did and Grover and basically anyone who had spent many years fighting side by side with the son of Poseidon. Percy was smart when it came to fighting. Did that mean Percy had a sure win? No, no it did not. Did he have the advantage? Yes, because he did not have to hold back like David was. But trying to keep slow, David was giving more attention to that than he was to fighting. Had David been able to use all his powers and speed, Percy would have had a much harder job of it.
David was not taken by surprise when Percy was able to push him away, however it did take him a few seconds to correct himself so he didn’t knock himself out on the landing our anything like that. “Nice new move Perce, you should use it more often” The son of Zeus said appreciatively, not at all mad that it had been used against him. This was a fun fight after all. David knew that was all Percy and him would ever have, fun fights. They may not be brothers by blood, but that only made them that much tighter. They often shared the same views on things, this being proven by the fact they always remained on the same side no matter what disagreement the Avengers had. Never would they meet on the battle field to find themselves enemies and would have to go for the kill... they would sooner slit their own throats.
The block threw David off balance a little, which did nothing more than anger him. He knew concentrating on his speed was a weakness Percy was willing and going to exploit. He had accepted that.. However now that it was actually happening, it made David mad. Not enough to through the terms of the fight of course. He was more frustrated than mad. He knew in that moment he could not win this fight.. Not while he was fighting his own instinct to use his speed, strength and powers. Had this been a fight where instinct was allowed, David knew he could win. Was David going to throw the match just to end this quickly? No.. Not likely. However he knew eventually he would mess up... or be too slow... or instinct would kick in and he would throw the match, thus giving Percy the win. So he was not going to win this match.
The stab towards his midsection David barely was able to block in time, as he was still in motion from his own slash. As it was Percy did succeed in getting a scratch.. However not in David’s skin, just his clothing. For a second this distracted David as he looked down to make sure he had not been nicked. Of course Percy had taken this advantage and stuck again. David realized too late though. He had just been looking up and saying “Ha! Missed!” when Percy’s second strike hit his midsection, the magic blade cutting through his suit and then into his side. Not deep enough to kill him, but enough to hurt like Hades and cause major bleeding. David twisted away hoping he was fast enough to somehow have Percy miss him, even though David had already felt the cold blade sink into his flesh.
David backed up a few steps, keeping his sword up. He then pressed his hand against his side, pulling it up to find his hand covered in red blood. Now David could have kept fighting had this been a real fight.. And he would have. He had sustained an injury quite like this one during the Battle against the Chitauri, because of his suit caving in to cut his body. David had still fought the rest of the battle only hindered slightly from the pain. However David also knew the consequences of such a thing, as the loss of blood had almost killed him.. Had Eragon not used his magic David would be dead right now. So David sunk his sword into the dirt and leaned on it. He then coughed before saying “Good one Perce. I’ll get you back for this one day I swear” Of course he did not swear on the river styx because that would be bonding, and David was not serious. The small grin that appeared on David’s face confirmed this.
The Son of Zeus then looked at the crowd and said “That is why you let nothing distract you in a fight. This is also why you never hold back unless you can easily outmatch the enemy. Had I been able to use my powers, strength and speed, this fight may have gone very differently. Percy, any more tips for them?” He then fell to one knee, so that the strain from standing up did not cause him to bleed out. He would go for medical attention afterwards.. They still had a duty to the Demigods.. David never shy-ed away from duty.
