As do many DVDs, Harry Potter and the Deathly Hallows Part 2 contains a number of deleted scenes.
In one, Harry and Luna Lovegood engage in a conversation at the grave of Dobby the House Elf. He rescued them (and others) when the Death-Eaters held them prisoner at Malfoy Manor. As they made their escape, Bellatrix Lestrange threw a knife that struck and killed Dobby.
Harry is about to set off with Ron and Hermione to find a horcrux in the Lestrange’s vault at Gringott’s. Luna will return to Hogwarts. They exchange the following words as they part.
Harry: Hogwarts? It’s the not the place you left, you know. It’s not the same.
Luna: Neither am I.
How many situations do those words fit?
See you along the Trail.
