The Only Traitor

"I never thought I'd die from poison," Remus mutters into the dusk. "And I certainly never thought it would be from you." It is here that Sirius deceives Remus, with three drops of Veritaserum, into telling him the truth he does not expect, but yet, always has. A truth they've both always known but yet never have at all. And it's lethal. A Wolfstar fic written for SilverOwlMalfoy.
