Maybe that was it, Finn thought. Maybe he could hold back the anger because he knew that they all knew now, better than any shouting match could have told them. He wasn't one for beating an already very dead issue. He frowned. "I realize you all probably won't be making that mistake again," he said. "But I also realize that the attitude of the greater good and blah blah is still there. Just..." His frown turned to a scowl, and he moved his hand to the side of her jaw, looking into her eyes and brooding with it. "I'm never going to like watching you abuse yourself for other people who I don't really care about," he informed her.
It was certainly true that Finn didn't seem to care deeply about the people around them - he was pleasant when approached, helpful where possible, but he didn't have the kind of connections that she did. Clearly he was capable of them, but there was just something in the way, for him.
