Remus listened, but he was still pretty upset about the whole thing. If Severus didn't know what happened, then how was he going to be able to fix him? And what was this about doing 'work' on Sirius? He didn't know if he could trust the Slytherin, and it was going to take a hell of a lot more than what Severus just offered up for him to be able to convince Sirius to trust him. It would've been hard enough before any of this to convince Sirius to go anywhere alone with Severus, but now?
He shook his head. "No, you've got to tell me more than that. He'll never agree to something like that unless you tell me what you plan to do." Even then, it would be like pulling teeth to get Sirius to agree to letting Snape help him. "Or tell me what it is and I'll learn how to do it. And you can keep holding anything you want over me."
