Casey is standing in the doorway, taking in the scene for a few minutes before anyone notices he is there. He watches Natalie hug Jeremy, and he sees that Dana is about to crack. He is also the first to see exactly what Danny's problem is. He knows what he needs to do, but he knows that he can't do it yet. Danny is watching him now, and they both know what the other is thinking. And then everyone else looks up.
"Casey!" Dana gasps, and she gets up from her seat on the couch. He opens his arms, and she falls into them, burying her face in his t-shirt. He looks around the room at the rest of them, rubbing her back methodically as she finally starts to calm down. Only his presence would eventually calm her because it would mean he was ok.
The same doesn't necessarily hold true for the rest of them. Jeremy has been unable to calm down since he first lost control, and Casey gently disentangles himself from Dana and walks over to where Jeremy has turned once again to face the window. He puts his hand on his shoulder and squeezes, hoping to let Jeremy know that he understands, that he saw it too, that he knows it's too much to bear and he can't possibly feel badly for the way he is reacting. He's hoping to convey all of this in one touch, and because he has remained silent and hasn't said 'it's going to be ok,' Jeremy seems to understand. He turns slightly and smiles tearfully at Casey before turning back to the window. Natalie, too, smiles at Casey but then puts her arms around her boyfriend again, holding on tightly as if she will never let go. She probably won't. Casey watches them with some sort of happiness… this may be one of the only positive moments of the day. He is trying to appreciate it as much as possible because he knows that what he has to do next will take all of his willpower. He is the only one with the power to get Danny to talk, but he knows what the price of that will be, and he hopes he's up for it.
Taking a deep breath, steeling himself against the inevitable, he walks over to where his silent friend is now sitting alone on the couch, once again seemingly transfixed by the television. He sits down next to him and for a moment, he waits to see if Danny will speak first. When that doesn't happen, though, he turns to him and says quietly, "when did you find out?"
Danny opens his mouth for the first time that morning, but no words come out. Casey can see that he is afraid of what will happen if he starts to talk, so he gives him a little more time. He knows that he is the trigger for Danny and that if he really wants to get him to open up, he can, but he is loathe to do it in front of all of these people. But there is nothing for it. Danny needs to talk. Casey knows he is only hurting himself more with his silence, so he does the only thing he knows that Danny won't be able to resist.
He slides over on the couch and whispers, "I'm so sorry about it, Danny… so sorry." He puts his arm across his shoulders, and Danny stiffens at the contact he did not initiate but now cannot escape. Because he suddenly feels his will crumbling, and he blinks quickly, trying to fight off the tears that have risen without warning. He looks down, shaking his head as if that will stop the emotions he is still not ready to face, but nothing can stop him once he starts, and he does the only thing that seems natural. He turns into Casey's shoulder, and Casey puts both arms around him resignedly as Dana, Jeremy and Natalie suddenly turn toward this very new noise. Danny is crying.
