Summary
Analysis
Scorpius finds Hermione in the underground hiding place, and Hermione immediately pins Scorpius to the table in fury. Snape assures Hermione that Scorpius is not a threat, but she’s not sure. Just then, Ron enters, also aghast to see Scorpius, but Snape again assures them both that he’s trustworthy.
As Snape leads Scorpius to the underground bunker where Hermione and Ron are hiding, it shows how Snape (and Hermione and Ron) have continued to put themselves in harm’s way to fight for Dumbledore’s cause, highlighting them as heroes for doing so.
