InuYasha was confused. "Huh?" he said unintelligibly. Sesshomaru's smirk couldn't get any wider. His brother was always so entertaining, whether he was smiling and laughing with his humans, fighting weak demons, or putting up his little "I hate my asshole of a brother" front.
Trying not to laugh again after having already broken his facade of indifference, he said "Would you like to join me on a trip to my home, our home, little brother?" If he thought he was confused before, InuYasha had thought wrong. Did his brother, The Sesshomaru, just ask him to come with him to the western palace AND call it their home.
"Huh?!" was all he could reply. Sesshomaru tried, he really did, but he couldn't hold in his laughter anymore and almost fell off of his perch while laughing. InuYasha just stared at him for a few moments while he tried to get himself back under control before asking, "Don't you hate me? Aren't I your dirty, half breed, mistake of a brother?"
That had Sesshomaru pausing for a second to think of a response. After a few seconds he said, "Not hate per say, but I would prefer to discuss this within the confines of the palace where we cannot be disturbed while we, how you say, hash out our past."
"Let me get this straight; you want me to come with you to the palace, so we can talk about you being a complete dick to me for my entire life, and I'm just supposed to go with you? Are you fucking kidding me right now?!" InuYasha asked incredulously. Sesshomaru simply nodded. This reaction made InuYasha furious. "I mean so what, I've been following him for a while now and basically being a stalker? I was just trying to find some dirt on him. It's not like I can just fucking drop the past like it's nothing!" he thought to himself knowing he was just looking for excuses.
"You can come with me willingly, or we could have a repeat of our trip here." said Sesshomaru calmly. "The nerve of this guy!" thought InuYasha. Out loud he said "Before I decide whether to come with you or not, I wanna know why. Why the sudden change of heart? Why do you suddenly feel sorry for how you treat me?"
Sesshomaru couldn't respond. InuYasha did have a point, he couldn't just have a seemingly sudden change of heart. He hummed softly then looked seriously at InuYasha, "How can I prove to you that this isn't just some ridiculous waste of time and that I'm actually willing to end our bad past and hopefully start a better relationship between us?"
InuYasha was stopped short. The sincerity in Sesshomar's voice was almost tangible. He couldn't act like he hadn't heard it. Instead of acknowledging it though, he turned his nose up and snorted then said, "You could start acting like it, to begin with."
To say Sesshomaru was surprised by InuYasha's response would be an understatement. He honestly didn't know how to go about acting like a brother should. He'd always been mean to InuYasha out of instinct. He felt like it was his little brother's fault that their father had died. He didn't hate the hanyou, he was mostly angry that his father had left him to go be with his human and hanyou son, leaving him behind. He was young when his father had died, but he was still as prideful as he is today. He would have never willingly gone with his father to protect a human and hanyou. It was too far beneath him, as a pure blooded youkai, to do such a thing.
They were at a standstill for a while until InuYasha turned away and without a word started walking off. He was extremely angry.
