"Yeah."

It's as instant as he can manage, his eyes shutting briefly because it's too much to keep his eyes open, for a moment. There's an odd nausea forming in him that isn't because of the concussion, as he starts to process what Remus means-- what he must have assumed.

"She was... gonna kill me, Moony." His eyes open again as he starts to speak, fighting and failing to hold Remus' gaze, "Already had-- Crucioed me. Tried t'make Reg do it, too."

Words are hard. Thinking and speaking is already exhausting, but this feels crucial. This is clearly a wrong he needs to right.

"He couldn't. Wouldn't. It got... bad." A shadows passes over his face; the memory already a haunting hurt, "He... c'nvinced her to-- keep me alive. Made it hurt less after she-- left."

And now he can't help the guilt that creeps over his face; the way he tries to shift his head to find his brother's still form, "Was tryin'-- t'tell you."

But the words had obviously not come out right at all.
