Ree, is Sash wakes up, Justin will be there for him no matter what his condition is. Just like he's been for Justin. It's not Sash waking up Justin's terrified about. I'd wager a bet that it's because he doesn't understand why he still feels like he can't keep living when it's all he wants Sash to do. No matter how much you try, that's not something you'll ever be able to empathise with. He knows no one can and he's probably feeling really alone. So, just remind him he's not, as many times as he needs to hear it.
