Familiar faces populate the teaser: Harry, Aunt Petunia, Ron, Draco, Severus Snape, wandmaker Ollivander, Professor McGonagall and the lovable giant Rubeus Hagrid all make appearances. Hagrid, in particular, delivers a warm and resonant message to the young wizard about the courage and kindness of his late parents, while Ollivander — ever the sage — hints at a destiny too large to ignore.
