Final Chapter ---- Does Luna leave Hogwarts on the Hogwart's Express ?

[yale sam wahl]

No: HPFGUIDX 69301

Did anyone notice that Luna was NOT mentioned as being a passenger on
the train ride home from Hogwarts???? {pgs 864 to the end of book)
Was she still at Hogwarts finding her belongings, or what ? And why doesn't
anyone miss her ?
Then notice that Luna IS mentioned as being on the homebound train in the
Harry Potter Lexicon's brief chapter summary for Chapter 38.
Hmmmmm ......... any thoughts ?
