When they entered the chamber of the foul creature that resided inside the castle, Ganon met them with an evil grin, thinking he would be too powerful to be beaten this time. Indeed, Ganon was not as easy to defeat this time as he was the last time with a new technique or two up his sleeve.
Instead of in the previous fight he had with Link, Ganon had completely dropped his style of disappearing and firing balls of fire at Link. Instead he stood there, beckoning the two to fight him, convinced that he could not be beaten by the two of them.
Before either of the two could react, Ganon quickly delivered a magical blast in their direction. Doing the only thing possible, Link grabbed Zelda and jumped barely out of the range of the attack. Had they not dodged the attack, they would likely have immediately lost.
As Link got to his feet, Ganon was there, ready to deliver yet another strike. Wishing to delve into a different way of battle, Ganon drew a sword. Seeing that this might actually get interesting, Link drew his sword and shield, ready to fight as well.
The swordfight started out as a match between two skillful swordsmen. For every strong strike that Ganon made, Link was ready to block it; likewise, as Link attempted to deliver a powerful strike to Ganon, he parried the blow with his own blade. Neither quite seemed to gain any ground in battle, as they seemed evenly matched.
Thinking for a moment that Ganon had forgotten about her, Zelda crept behind him, ready to fire a blast of magic. However, that tactic didn't work, because, after blocking one of Link's more powerful strikes, Ganon took his left hand and sent a blast of magic in Zelda's direction. Unlike the last time, Ganon's blow connected with the young Hylian princess.
The force of the blast knocked the young woman backwards and against the back wall, seemingly rendering her unconscious. Seeing this unfold, Link let his guard slip for the slightest fraction of a second. However, that was all Ganon would need to take an advantage in his swordfight with Link.
Figuring that Zelda would be out of the battle for a while, Ganon took the offensive in his swordfight with Link, relentlessly delivering a number of expert swings and swipes of the sword, pushing Link back with each attack, effectively backing him into a corner with Ganon ready to strike the decisive blow.
However, when a hero such as Link is backed into a corner, the fight becomes infinitely more interesting. Once in the corner, Link regained the focus he had let slip for the slightest second and rolled out of the way of Ganon's strike right under his nose (literally between his legs).
Since the fight was back on even terms, Link again fought strike for strike with the powerful Ganon. However, though Ganon was powerful and skilled with the sword, he lacked the experience that Link had spent many years perfecting, especially in his attempt to rescue Zelda.
While Ganon's blows were of proper form and power, Link saw that he wasn't very fast in his attempt to deliver his strikes. Considering a new strategy as a result of this, Link backflipped a number of times, trying to force Ganon to charge after him.
Luckily, Ganon followed suit, and Link rolled out of the way of the charge and attempted strike, delivering a blow to the back of Ganon's head with his sword. After sustaining that blow, Ganon was momentarily stunned. In an attempt to rush his defeat, Link fumbled for his silver arrows, but couldn't find them amongst his other items.
When Link realized that he didn't have the silver arrows on his person, he heard a loud yell from the other side of the room, "DUCK!" Realizing that the voice belonged to Zelda, Link immediately followed the command; quickly an arrow came whizzing past his face, connecting powerfully with the skull of Ganon.
As with the last time Link and Ganon fought, the one silver arrow finished the fight: the arrows would always certainly defeat Ganon. Realizing that the mighty pig-like foe had been defeated, Link ran over towards Zelda and tightly embraced her, overcome by the joy that Ganon had been defeated but more joyous because Zelda had been the one to deliver the final blow (after having been captured twice previously).
After overcoming the initial shock of the moment, Zelda relaxed her tensed muscles, and returned the embrace. Though he was tired and somewhat weakened by the battles in Ganon's castle, Link was her hero, not only for rescuing her but for coming to know her as nobody else quite had.
When they exited Ganon's immense fortress, the two overlooked the landscape of Hyrule, noticing that the lack of Ganon's presence almost immediately seemed to lighten the air and bring the hints of new life. Each looking into the other's eyes and then to the land smiled with a sense of relief and heartfelt joy. Things finally were looking up for Hyrule.
Returning her glance to Link's face, Zelda started to say, "Hey Link?"
In response to that, Link asked, "Yes?"
Without giving him chance to react, Zelda quickly gave him a kiss, saying, "Thank you," afterwards.
Link, ever the hero he was, said in reply, "No problem, Zelda. I'm just doing my duty."
Through a small blush, Zelda smiled, looking directly at Link with those sparkling blue eyes of hers, and asked (albeit somewhat unorthodoxly), "Link, I know you're not of royal blood, but I'd like to know if you'd still marry me?"
"Zelda," Link said simply, "I'd do anything for you."
