Keegan returned from a mission. He failed it, causing many people to die. He felt absoluetely horrible, like a failure, who couldn't protect anyone. When he came back, he looked exhausted and drained. The others asked him if he was okay, but he simply nodded. But when he was finally alone with you, he broke down.

He lays in your arms, sobbing like a little kid. "It's okay..." You mumble, gently caressing his head. But he just clings to you for dear life. "It's not." He sobs, burying his face in your chest. "It's okay..." You say again. "It's all my fault!" Keegan cries out. "It's okay..." You say once again, soothingly rubbing the back of his head.
