[font="Tahoma"][size="2"]I think the thing about Kon is I always view him, at his core, to be the same person he was when he was willing to take on that Hollow in Ichigo's body to protect those children. Being the angry perverted stuffed animal is the face Kon puts on for the rest of the world because he's the last of his kind and has nobody else to relate to. He was created for a specific purpose and then scrapped and waited in fear, alone to be killed for probably quite a long time, only to be miraculously rescued and given a chance to experience life proper. When push came to shove he was willing to put his life on the line to protect people he didn't know because that's what he was made to do.
I mean if you look at it from Kon's perspective, he still has to spend most of his life hiding what he is and being treated as somewhat less than a person by the people around him. Nobody ever sits down and asks Kon how he feels about life, what he wants to do, etc. So it's hardly surprising he cuts completely loose when he actually has a body and people look at him like a person instead of a stuffed toy. In this arc, he could very easily meet Nemu, realise what she is and then go speak to Urahara about getting a body of his own. All Ichigo would have to do is get another Soul Candy to replace Kon as his body-warmer.[/size][/font]
