Sokka Mai.
After katara was killed in battle, Sokka no longer looked upon his eligable females with favor. Suki and Ty Lee were too chatty and ditzy for him, far too silly. Even Toph, who's sarcasm had once brought a laugh, now only was hurtful, and pointless. Ty lee and Mai had joined them after the comet. Mai's serious, melancholy solemnity was a perfect match for Sokka's angry, pained soul.
Zuko had died gallantly in an Agni kai, with his sister, to save katara's life. Unfortunately, his ultimate sacrifice had been in vain. Katara started to choke Azula when she was chained, and Azula chocked her back until thier hands accidentally froze together, and they couldn't let go. Each girl chocked each other to death, and then conitnued until the sun was high in the sky the next day, when they had been found in that position by Suki.
Aang had been killed while in the Avatar State, this time permanently. No hope for peace even pretended to exist. Appa and Momo had died inexplicably when Aang had, only minutes after katara had died. No one had the will to pep talk anyone else. Mai and Sokka had a silent understanding, they could completely relate without talking, after the three died. No one was upset about Azula, but Mai knew that Sokka loved Katara, although not the way she loved Zuko, just as much, and Sokka knew vice versa how much Mai loved Zuko. They never spoke, but when they were dragged out of thier lonely rooms, they drew together unconciously.
A month or so after the Comet, the five were hiding at the Western Air Temple. Sokka always sat next to Mai. One day, randomly, next to the flickering light of the fire, which mai was silently cursing, Sokka asked mai," Will you ever love someone other than Zuko?"
Mai thought about it for awhile, and said, It would take one hell of a guy to take my heart. Besides, we are all doomed anyway...". They weren't flirting, Mai had no thought of Sokka as that kind of guy. But two nights later, when Mai was asleep, Sokka knocked on her door. Mai woke groggily, and mumbled,'Come in..." Sokka entered, and sat right next to Mai on her bed, looking somewhat troubled. He was never sarcastic, good humored, or in any way the boy he had been. He had grown quite a bit. Mai only had on her breastband and underwear. She sat up next to him, slightly concercned. He was the only one she cared about anymore, at all. She felt his hand suddenly enclose her's. He didn't kiss her, he didn't announce his love to the world, or look dreamily into her eyes and say, " You know, from the first moment I met you..." He just took her hand in his, and looked at her. And she knew she returned his unspoken sentiments. She was surprised, but nodded imperceptibly. And she was his and he was her's and that was that.
The next day, they were having breakfast, simple bread and water, when Suki ran over to the group, a wild expession of fear and disbelief." What, Suki?" Asked Ty lee in her ignorant way. Suki cried," Fire Nat-" the wall exploded in flame interrupting her before she could finish, smashing her into the wall, where her neck broke instantly. Ty Lee was on fire, screaming, rolling around. Toph was running about wildly, trying to grab rock and dodge fire she couldn't sense. Yue cried "Everyone for themself! maybe someone will live.." just then a huge flame blew threw. Sokka and mai looked at each other, and signaled partnership, that they would stay close. They jumped up, and ran out the back of the temple. There used to be a huge cave, that was really a hiding place, but now, there was a huge platform eith only a floor.
It was storming ashes, a blizzard of burning embers and black smog. They coughed, and watched in horror, as huge bombs came toward them from far above. There was nowhere to run. Sokka looked at Mai, hair undone and loose, thick and black, eyes huge with terror, and cried," MAI! I love you!" Before she could reply, he grabbed her enveloped her in a kiss so passionate, even Aphrodite would've fainted. Mai didn't respond, but didn't have to. Her lips said it all, and they embraced as their destiny, their end, their fate, rained down from the heavens in the form of fire and rage.
