I know thinking about what good it does - or, how right you are that I'll never blame you - can't just fix this. What happened was too senseless, it was unfair. [To you, to both of them. They'll have to remember it for the rest of their lives. His voice softens, pain there inevitably, but also a kind of urging.]
Shiro, no one has been through what we have. No one ever should've had to. But we're still here... We'll still have each other.
[You have him no matter what.]
I'd tell you every day that you're worth forgiving if it means you can afford yourself that one day again too. You deserve to, after everything you've been through.
