I'm sure Greyback would take the greatest pleasure in letting Remus know that any plans to scupper the night's events had failed - because he is so utterly twisted, and would enjoy playing games with life and death. Which would also be enough to drive anyone to despair over what good they thought they were doing against someone like that, I imagine.

I'd quite like to write some more fic with these two playing cat and mouse, so you may get that backstory, lol. And, thank you. :)
