It's strange, Gin, what's wrong? He has become an expatriate recently. It seems as if he prefers to just be alone without anyone bothering him. That's okay. Maybe he doesn't want to tell anyone about what's on his mind.
You sometimes thought about talking to him about the reason for that since his only positive relationship was with you, but you only thought about following him sometimes and seeing what he was doing, just walking around the Seireitei... it's not important.
But as soon as the big battle against Aizen broke out, then... Unfortunately, it turned out that Gin was also a traitor. However, he tried to save you from Aizen by lying about killing you, but when Aizen saw you alive, he stabbed Gin as punishment for his lie.
Here's he, lying down there and bleeding..
