Axel is confused. No, he's more than that. He is completely conflicted. What happened back there? In his mind he could see Larxene's electric blue eyes soften in bewilderment and her mouth go slack. He had passed off the incident with a laugh and left after he had finished eating. As he took the back road to his home he was starting to come to some serious conclusions.
First, he was now attached to four girls instead of three. This wasn't his intention at all. He had the ability to divide his heart and his mind in order to obtain what he wanted. He preferred sex over love (because love was an illusion), and proceeded to be as shallow and self-serving as he could be. He wanted to seem careless so no one could blame him for his actions and excuse it as his "typical behavior".
Second, he was running out of excuses. Namine had figured him out, how long she had known this is anybody's guess. Xion may still be oblivious, but Kairi was more attached than he realized. She has actual feelings for him and it was showing. He was losing control on her. And what was worse was how he was beginning to have feelings for her. What these feelings were exactly, he didn't know. All he knew was that he didn't want to find out how deep they actually went.
Third, there was Larxene. Larxene had been a completely random loop he wasn't prepared to deal with. She was in left field and came completely out of nowhere and proceeded to fuck his life up even more. She was like a wild card somebody else was using. He had no idea what she was capable of. Originally he had thought she just wanted to fulfill some vapid sex drive she possessed, but that didn't quite seem to be the case anymore, now did it? As he walks through the front door he ponders that she might not have foreseen her own feelings coming into frame.
His fourth conclusion didn't come until he reached the living room where someone-a young man- was sitting on the couch. Axel recognized him instantly: red hair, green eyes, same face, same build...
"Hey, brother," the voice hit Axel's ears like a ton of bricks. The young man stood up, matching his height, mirroring his face and just about everything else except his name. "I've come home," he said in a nervous, unsure voice. Axel swallowed haphazardly, the words not forming in his mind. He had nothing to say that he could think of. He couldn't feel anything inside of him. The shock was overwhelming. This was exactly who he thought it was.
"It's been a while, Reno", he managed to choke out after a long time.
The two stood there looking at each other, not saying a word. After all this time-a year-someone he had all but forgotten shows up again out of the fucking blue and dares to try to act normal. Actually, Reno isn't looking normal. He's thin, a bit dirty. His face is a bit bruised and he's recovering from a black eye that he got God-knows-where. He's nervous, a bit scared looking too. He can't even hold eye contact for a moment.
Axel hates the would-be stranger. He hates how he dares to have his face, his blood, his parents. He shows up now? His twin brother dares to weasel his way back into his life after a year of deciding "Fuck it, I'm gone"?
"You mind telling me where the fuck you've been?" Axel's voice is shaky. He forgets about the girls and his issues and focuses on the one in front of him. He feels his hands clenching to fists. Reno doesn't answer. "Where the fuck were you!?" he screams and before he knows it, his fist has collided with Reno's jaw. Reno falls. Axel is right there next to him, fists flying. He can only say one phrase, one question.
"Where were you!?" he screams. "Where the fuck were you!?" Reno doesn't answer, only defending himself against Axel's poorly aimed flailing fists. He wants to hurt him so badly. How could his only brother just up and leave? Axel wants to know. He can't see straight because of the tears in his eyes. His throat begins to go dry from the extended use of his vocal chords. Axel begins to slow down, he's running out of emotion. He doesn't have any rage left. He finally stops and looks at his brother laying there, slowly coming out of defense mode. He sits up and crosses his legs, looking at the carpet. Axel does too. It's almost like when they were younger. Not a single word passes between them. Reno still hasn't answered Axel's question. Their parents still aren't home.
"Get a shower you asshole," he tells Reno as gets up and walks upstairs, "You smell like shit."
