I really enjoyed this story, particularly the Severus/Minerva pairing, as that's one of my favorites. You handled it so deftly and believably here, it was a pleasure to read.
There were a lot of good lines, but I think my favorite was: "Severus, ye cannae go mad. Ye hae not the luxury." Somehow that just seems to sum up so much of Severus' life. Very well done. :)
