This scene takes place right when Axel comes to save Sora from the mob of surrounding dusks. Axel uses up his entire energy force with his fire attack, and collapses onto the floor. Sora kneels beside him and listens to Axel's dying words.
"I wanted to see Roxas," Axel mumbled with his last breathes of air, "He… was the only one I liked… He made me feel… like I had a heart."
"Axel…" Sora sighed. The look in his eyes was what you could only expect from someone that was merely an acquaintance—he felt pain, of course, but he couldn't feel the full extent of it, like what he would have felt if this were Kairi or Riku lying there on the ground.
Then, as if a bolt of lightning had hit him, Sora's face fell blank. There was no longer any pain or grief. He could have been asleep with his eyes open as far as anyone would have been able to tell.
Axel became silent, staring weakly up at Sora with the small amount of confusion he could muster.
Sora twitched. His eyes grew wide, and his lips parted.
As fast as this bizarre, possessed look had taken a hold of Sora's face, it was gone, and had been replaced by an entirely different person looking out from his now glistening eyes.
Axel shot him a knowing look mixed with shock, and he saw that this was Roxas standing above him.
Sora was standing farther away, and decided that he didn't have any more time to lose if he wanted to save Kairi. He left, and the two remaining men ignored his exit.
"I missed you," Axel said as a tiny smile was spreading across his lips, and his eyes too began to glisten. "I'm so happy that you're the last thing that I get to see before I die."
Suddenly, Roxas's expression turned hard.
"No!" he exclaimed, "I'm not going to let you disappear!"
"Roxas don't," Axel protested, "You have to let me go. I'm… not worth…"
"Shhhh…" Roxas whispered gently, appearing to become more and more serene with every second. He placed his right hand on Axel's chest, letting his head rest there as he closed his eyes. He felt the thump of Axel's heartbeat, and became in tune with his breathing.
As much as part of him wanted Roxas to stop, most of him was in a state of bliss at the feeling of Roxas's body against his own in this sweet, caring way. He began to feel the darkness sweep over him. His eyes started to close…
Out of nowhere, a spot of light appeared at the place where Roxas held his hand. It slowly grew larger, spreading across Axel's body until he was completely illuminated.
Roxas lifted his head and opened his eyes. He stared down in awe at the glowing mass that was Axel as it rose onto its feet, and was eventually standing up straight.
The light faded away and there was Axel, standing with his hands on his hips, a wily grin taking up half his face. He belly laughed, and reveled with each deep breath of air that his lungs could now take in.
Disbelief was the first emotion that Roxas felt, which was quickly followed by the most joy he had ever felt in his life.
"Axel!" he shouted like he was seeing someone dear to him that had just come home from a terrible war. He ran up to his best friend, and wrapped his arms around him as he began to cry happy tears into Axel's Organization robe.
Axel pushed him away, but maintained eye contact. Roxas stopped sobbing so hardly, and began to gasp for air as if he were trying to stifle it. Slight hurt entered his eyes as he felt the coldness of Axel's reaction. He then tried to hide it with a pout.
Axel chuckled warmly, and then looked a little nervous. "Roxas, let's get out of this place. I need to tell you something important."
So he conjured up a portal to leave the Realm of Darkness. They walked through together, and when they reached the other side, they were on a white balcony at the castle in the World That Never Was.
Roxas turned to face him. "So, what is it?"
"Well," he said in a voice barely more than a whisper, "I just want to let you know how much you mean to me. The truth is…" he swallowed and looked at the ground, then looked back at Roxas, "you're the most amazing person I've ever met."
"Wow," Roxas replied, "I don't know what to say, Axel. Thanks, I guess…" He waited a few seconds to see if there was anything else he had to say, then began to walk towards the top of the castle, and said, "Well, I guess I have to go back to Sora now."
"Wait!" Axel stopped him by grabbing the sleeve of his robe, "What I really wanted to say was that I…" He hesitated.
Axel had been in love with Roxas since the first day he met him. He never told him because he thought he would just laugh in his face and never speak to him again. Axel had almost died, and now he was determined to tell Roxas how he felt about him, even if that meant he could never see him again. It had to be said.
A sudden burst of courage hit him. He took a deep breath and said, "I love—,"
Just then, a group of dusks appeared.
"Ged outta da way!" a shrill voice cried. They ducked, and a flash of ice flew above their heads and killed one of the nobodies. It was Donald, one of Sora's two dim witted sidekicks.
Sora, Donald, Goofy and Riku appeared, and they asked that Roxas and Axel would help them fight the dusks.
"Damn," Axel muttered under his breath, but they agreed to help.
After defeating the nobodies, Axel and Roxas decided to go along with them to kill Xemnas. They knew they wanted to anyway, and thought that they might as well do it with some help.
Axel wondered if he would ever get another chance to tell Roxas how he felt.
The ominous moon shone upon the six of them as they made their way up the balcony.
