As a Resurrectionist of the Snape and Sirius kind, I salute you! Harry's abnormal luck brought about three things I didn't believe possible: 1) Harry's feet would find the most comfortable bed in Hogwarts; 2) His phenomenal luck would bring him to wank in a place of potions; and 3) He'd realize that Alive!Snape is so awfully much better than Dead!Snape! *LOL*
The logic is skewed by sleep deprivation, but, the sentiment of wonder and glee is true! A great showing!
