Oh, yes, yes, YES!!! Oh, this is so post-HBP perfect! Poor, misguided Remus is so determined to get his digs in, and Snape is so placid for the most part, knowing the truth of course, exploiting the situation to get what he wants - a warm touch with someone he cares for. And best of all, it ends with Remus thinking he's on top of things! Poor, darling fool! This story is perfection!
