Harry needs to go to Dumbledore and see if his memories can find a answer in Dumbledore's Pensieve.

The dancing scene was very helpful, they all learned to start getting better at ballroom dancing.

Theo's narrative about his former aunt helped to build a positive relationship between Harry and him.

Tracey did a good job in beating Draco in Quidditch.

The prank from Gryffindor seems to have backfired and given Draco more support from Slytherin.

Pranking is a time honored tradition but don't take it too far.

Susan and Hannah will make good additions to the Slytherin study group.
I think there should have been a tryout to see who was named Slytherin seeker.

Harry does his best with his relationship with Dumbledore, but the old man strains it with his need to keep secrets. It will take time for that relationship to improve.

I think it's wonderful to share classes with all 4 houses.

It's big news that Harry is a Parselmouth and it's good that that information was limited to Harry's friends to start out.

It was good of the Greengrasses to make Harry their ward.

It's good that Dumbledore rescued Harry from the Dursleys and managed to bring him to the Greengrasses. I hope Harry's things can also be recovered.

The bad news of returning to the Dursleys brought down the better news of spending some time with the Greengrasses, and getting rewarded by the Flamels for recovering their Stone.

I'm glad Harry beat Quirrel and recovered the Stone.

Its very dangerous to take children in the Forbidden Forest. Hagrid should be punished for that.
