That time Sirius and Harry have their first heartfelt moment and Snape is just scraping his head on the low ceiling…
Recently reread PoA and one of the best and funniest moments of the book is when the twist unfolds and Harry believes Sirius. In the ensuing scene they’re headed back to the castle through the passageway from the Shrieking Shack; Snape under the mobilicorpus spell.
Sirius is guiding Snapes unconscious, floating body carelessly as he strikes up a very serious with conversation with Harry: the idea of moving in with him. It’s a very heartfelt scene and becomes important for Harry later, all the while Snape’s lolling head is dragging the ceiling of the low passageway.
Shame they took this out of the movie, damn shame.
