That brief compassion that Myrtle showed to Draco in HBP now turned into a full-fledged ETERNAL (pun intended) love romance :D
I'm still not really sure who made Draco sniff the violets from underneath but I would guess it might have been - mistakenly - some DE. A strange way to die and as such, might have led him to becoming a ghost.
Still intriguing, although you should update more frequently :D Good job!
