I'm surprised you got that close to them if that's what it was like. [Shun puts it very bluntly. He's had friends try to kill him - and almost succeed, for that matter - but that hadn't been when he'd met them. Unless Lavi got in that deep before they started behaving that way, but he can't really say given the circumstances.]

I'm guessing they're better than you're making them sound if you allowed him to name you and missed him that much when he disappeared - and care this much about her opinion - but if she spoke without thinking, it's not worth dwelling on. If they did it to hurt, dwelling on it is letting them win.
