not sure what's better, that knowledge for Severus that the repercussions - of every wrong choice, of every wrong move - would have been so disastrous; or that he gets his happy ending. Either way, he deserves this double gift! Imagine the relief one might feel at knowing that 'wrong' was -sort of - 'right'. Nice clean style, and a lovely parallel to Harry's time with Dumbledore at the end of DH. Many thanks
