"If I did my job James and Lily would still be alive." Sirius's voice was thick with emotion. At this point the only thing keeping him together was sheer force of will. He had more than enough practice at that.

"I didn't tell them not to trust you. I didn't want that." He placed his hand on the door jamb, not trusting he could stand for very much longer on his own. His body ached and all of this only made it hurt worse. "And the proof..." Sirius's eyes went from dark to blazing. "The proof is Peter's alive somewhere, waiting, biding his damn time. Do you think I like admitting he outsmarted me? Who'd have thought he had it in him?" His nails scratched against the jamb. He stared at them, just imagining the things he would do if he ever caught that traitor.
