A/N: This is my first fanfic, and it's basically what I imagine Renji's reaction was when he saw Byakuya smile for the first time in recorded history. One shot.
"Excuse me, Captain… Can I ask you a favor? You don't have to fill in for me at the vice-captain's meetings when I'm out, so please don't…"
"Part of a captain's responsibilities is to make sure the vice-captain's responsibilities are taken care of."
"Right, I understand that, but… wait, don't tell me you don't go to Rukia's Shinigami Women's Association meetings when she's out, do you?"
Byakuya's lips turned up ever so slightly. (A/N: OMG!!!). Renji stood there for a moment, then turned pale white. Either he was having hallucinations, which could be bad, or he was dealing with some kind of… imposter. Byakuya. Does. Not. Smile. He looked, and it was still there. Renji jumped up and pressed Zabimaru to Byakuya's throat, panicked. "What are you doing, Renji?" The smile was gone, thank God. "WHO ARE YOU AND WHERE ARE YOU KEEPING BYAKUYA?!" Byakuya, who was irritated and slightly alarmed at this behavior, merely shunpoed around his vice-captain, who was hyperventilating in the middle of the floor. "If you continue to yell and make a scene, people will come running. Please lower your voice," he reprimanded in his usual stoic manner. "Of course I'm really Byakuya. Can't you feel my spiritual pressure?" "For all I know, you could be one of Aizen's hypnotisms! If you're really Byakuya, prove it!" The sixth squad taicho let out an exasperated sigh. "If you really want proof… Scatter, Senbonzakura." A thousand shards hovered in the air. "Do you believe me now?" "You really…did…smile…"Renji fainted.
A/N: Yeah, this is just a completely random idea I had. Like I said, it's my first one so sorry if it seems OOC. Constructive criticism is welcomed and appreciated.
