When you realize it
It was odd standing before her like this, having these silent emotions arise by simply standing in her presence. But he would not allow those feelings to show, like all the many other times he would stand there with the unreadable smile on his face and that calming look upon his expression. Though behind his calming expression he wondered if a battle would soon go underway, in all honesty he would have hoped that it would not come to that. After all it was her, it wasn't anyone else, it was Rangiku, the only one he even showed a remote sign of care for. Even so it came to a thought, if Aizen-sama requested that he killed the woman before him, would he be able to do so? Even he couldn't bring himself to answer that question.
Her words returned him to the situation at hand, her response did not falter the grin that was placed on his face. He inspected her troubled demeanor, though her voice was cold and attempted to have a tone that was unreadable, even so that lovely face was obviously troubled. He hated to see her troubled in anyway, back then he would have tried to bring a smile to her face. However now it was him who was causing her ailment. He was in a bit of an awe that he found himself thinking of what to do. If it were any other shinigami this stalling would not have occurred, he would have without hesitation tried to slay his enemy. But what was he to do now? He was far too deep down this dark path to turn back, even for her.
"Rangiku." her name fell from his lips as he took a few steps forward. His swinging hand at his side tensed, conflicted in the decision of whether to draw his weapon or not. "Don't look so sad." he said with that ominous grin as in one step he disappeared from where he stood leaving nothing but a faint trace of his presence. He re-appeared a few feet behind her. "I thought you would be happy to see me~" he teased as he took one or two steps towards her. "but I see your not." he continued, slipping his hands within his large sleeves and allowed a fake hurt tone to cover his voice. The wind picked up slightly just then, carrying to him her familiar fragrance. He inhaled it deep and allowed it to bring back even more memories of her. He had to snap out of that daze, she was clouding his judgement, he would be a bit of ashamed if Aizen-sama was viewing this encounter. Though he wouldn't doubt that the brunette leader was watching.
"Now tell me, why have you come here alone? Or is it that your comrades been killed off already, how sad." Gin said with a chuckle. He was highly curious as to why she was standing before him in this hellish place alone.
