[Sirius listens intently. It's clear this is all very hard to admit, and he can tell that nothing is being sugarcoated or made to look less horrible than it is.

When the monster describes his anger, his desire for vengeance, Sirius holds his breath. Sets his jaw. When he speaks of his regret, his cowardice, Sirius lets that breath go.]

I...actually understand all that. It, er. Hasn't happened yet, but. I've read a story about my future. A book written by someone who knows what happens to my world. And to me.

[Sirius runs a hand through his hair, then drops it abruptly when he recognizes a habit he's picked up from James. His heart twists.]

One of my friends betrayed us and got two of my other friends killed. And me sent to jail, framed for it.

[Sirius realizes he's speaking in past tense, and numbly decides it isn't worth correcting. For all the times he's read the books, it may as well have already happened.]

I broke out, eventually, intent on seeking revenge on the person who betrayed us. And it's true that he had completely turned his back on his, had no intent of fixing his mistakes. He was too far gone. But...although I didn't betray my friends myself, had I been a better friend to P-- to the one who did betray us...

[He lets out another, tight breath.]

It hasn't happened yet, but I've felt angry and vengeful. And then just as embarrassed at my inability to see what I'd done to make this all happen until...well, it might already be too late, if we can't remember what we've learned here and go back home with it.

[Sirius swallows. This is really heavy for an event about dressing up and getting candy.]

So. I guess I can't say I'd be one of your, er, guard dogs. But I understand. And I'll be on your side if you need it.
