Chapter 1 - "The Worst Birthday" - In which we are reminded of the happenings during Harry's first year at Hogwarts, Uncle Vernon has a very important dinner guest coming, dinner plans are made, and Harry's birthday is forgotten again.

The Dinner Party and a Birthday Visitor
At breakfast, [Uncle Vernon] yells at Harry about Hedwig making noise, and the whole family goes crazy when Harry uses the word 'magic' in conversation.
Harry thinks back to everything that happened in his first year at Hogwarts, and we learn the story of his life.
[Uncle Vernon] reminds the family of the upcoming visit by the [Masons], making sure Harry knows to stay hidden in his bedroom.
Harry Meets Dobby
Sent outside by [Aunt Petunia], Harry plops down on a bench in the garden and thinks about how his friends have not contacted him all summer.
Harry notices two eyes staring at him out of a bush, and then, confronted by [Dudley], pretends he's setting it on fire and sends [Dudley] screaming back into the house.
Harry gets in trouble for faking magic in front of [Dudley], and the [Dursleys] shuffle him around the house, finally forcing him upstairs as the [Masons] arrive. Once in his bedroom, however, Harry discovers someone is sitting in his bed.
Chapter 2 - "Dobby's Warning" - In which Dobby, a house-elf, arrives in Harry's room to warn him not to return to Hogwarts, the Dursleys' dinner party is ruined by Dobby's antics, and Harry is locked securely in his room.
Harry Meets Dobby
With the [Masons] downstairs, Dobby talks with Harry, marveling at his triumph over Voldemort and warning him not to return to Hogwarts, but stopping every time he does something bad to loudly punish himself. He also admits he's been stopping Harry's letters, but when Harry refuses to promise he'll stay home Dobby runs out of the room.
