Bakugou and Kirishima were fighting... They never fought, the two were fighting over the gem and Bakugou was saying that they should just drop the whole thing with getting you home and that they should stop before it gets you all killed. Kirishima fought back with saying they should still bring you home. But then Bakugou shouted out that they would find a home for you there.... In their world and not take you home..... It broke you. You thought Katsuki cared about you but obviously he didn't. You looked at the two and ran off into the woods leaving them.
