Analysis
When Albus looks up to find Ginny, Harry, Ron, Draco, and Hermione, he runs into Ginny’s arms, thrilled that they got the note. Draco and Scorpius hug awkwardly, too. Albus explains that Delphi is trying to kill Harry before Voldemort attempts to do the same and inadvertently curses himself. Hermione deduces that since they don’t know where she’ll be coming from, they need a place that gives them a good view of the town while keeping them hidden—like the nearby church.
The primary characters are now all together, and a reconciliation has begun. Of course, that reconciliation is not yet complete, as is made clear by the fact that Albus runs into his mother’s arms rather than his father’s, and by the awkwardness of Scorpius and Draco’s hug. Nonetheless, it is a start.
