The blood. [ He says softly. ] There... there was blood on the back of your shirt. When you first came here. You.... you said you weren't hurt anymore.

[ His gaze lifts again to meet Billy's. He feels like he's just on the verge of things, like it's on the tip of his tongue. But he can't quite grasp it, can't quite put words to it. He looks for understanding, for Billy to put the words to it. ]

It.. wasn't simple, coming back. [ He shakes his head, uncomfortable. He doesn't want to think about it. But the context is important. Kieren wishes he could look at it all with a more hopeful lens, but there's just... too much. ]

I wasn't... entirely myself. Like, y'know. Up here. [ He taps his temple with a finger. ] Not at first. We... people like me take medication. But before that medication—

[ He swallows thickly. ]

I hurt a lot of people. People died. [ There's a beat. ] I— I came back like this and I did so much wrong and I— I can't let go of that.
