This transition scene shows us a variety of little scenes. Scenelets? Scenettes? Scene Lites?
The Sorting Hat sorts both Scorpius Malfoy and Albus Potter into Slytherin.
No, we're not speaking Parseltongue. A Potter just got plopped into Slytherin.
Not only that, but Albus has trouble getting his broomstick to rise—a euphemism if we've ever heard one—and students tease him as the "Slytherin Squib" (1.4.49).
Before Albus's second year, Harry encourages him to find a friend. Albus says he has Scorpius. "I know you don't like him but he's all I need" (1.4.69).
Later, Draco asks Harry a favor: dispel the false rumors of Scorpius' parentage.
Harry refuses.
During Albus' third year, Scorpius' mother dies and he asks Albus to accompany him to the funeral.
Finally, we see Lily Potter sitting under the Sorting Hat.
After managing to rhyme "Gryffindor" with "Ravenclaw" (Ravenclawr?), the Sorting Hat sorts her into Gryffindor.
Albus remains the only Potter in Slytherin. We hope he looks good in green.
