Spoiler Alert: My interpretation upon reading chapter 423. Not that far yet? Better not read this...
Not Okay
She stared at him, her gaze never breaking from his, watching his face grow sadder and more forlorn as what little time they had left together slipped away. She knew she was fading from his eyes, from his life. The playful banter fell between them, as realization dawned on them both that this was going to be it. Forever.
"Give everyone my best," Stupid Ichigo and his tough guy act. How could he just stand there and smile at her? He was no longer the boy who had stood there and screamed when she had left with her brother and Renji for Soul Society. And he was now so much more than the man who had stood across from her in the fading sunset, as she said goodbye to him the first time, and he had accepted it calmly and understandingly. Even now, devoid of all the power that had initially brought them together, he was still so impossibly strong.
"Okay," was all she could manage, her gaze slipping from his at that precious final moment, betraying everything she had been trying to hide from him.
Then the moment came when he was no longer looking at her, but rather through her, and then all of her carefully constructed Kuchiki restraint vanished into thin air as she vanished from his life.
"Thank you" his softly uttered words, so sincere, drained her of her strength and the tiny shinigami collapsed down onto her knees, glad that he could no longer bear witness to the emotions she had so desperately sought to hide from him.
With their friends in the doorway, maintaining stoic faces with averted eyes and half smiles so as not to alert the ex-shinigami to the sudden state that had befallen his closest comrade, Rukia wept openly at Ichigo's feet.
This is what I envision happening after Rukia fades from Ichigo's view. Afterall, it's not like everyone else just magically stopped seeing her right at that moment? She was still right there correct?
