So happy to see an update! (Hope you enjoyed HBP). Wonderulf as always - the plot thickens and it really made me happy to see Draco's fellow Slytherins supporting him. Loved the bit with Pansy at the end. As for continuing the story and what part HBP should play - I say do wahtever you creative juices tell you to do. If you left it in your universe that would be fine, if you choose to update it to canon that would be okay too. You are a wonderfully gifted writer either way and I say do whatever your creative muse is telling you to do.
