Will Parvati and Lavender become ghosts???

I was listening to my PoA tape, again, and a phrase leapt out at me 
in Chapter 8 "Flight of the Fat Lady."  From PoA US hardback edition 
page 142:

"(Harry) couldn't like Professor Trelawney, even though she was 
treated with respect bordering on reverence by many of the class.  
Parvati Patil and Lavender Brown had taken to *haunting Professor 
Trelawney's tower room* at lunchtimes..."

Maybe it's just because I've been reading too many posts regarding 
the meaning behind minutia, but it made me wonder if Parvati and 
Lavender will die in one of the next two books and become ghosts.  Or 
is it just a simple statement to show how PP and LB hero worship 
Prof. Trelawney?

Of course the next question is: "Why would they need to become 
ghosts?" A first thought is for them to help Harry understand death 
and why some wizards/witches become ghosts.  But since they would be 
staying in Prof. Trelawney's tower room, would Harry even be going up 
there and talking to them?  He doesn't like Prof. T so why would he 
want to hang around there even if it was to find out more about the 
death process.

Another thought is that they would be there to keep an eye on Prof. T 
while Dumbledore waited for her next prediction.  Seems like a waste 
of two people's lives, though, just to babysit Trelawney.

Anybody else, with a better imagination than me, have any theories?

know they use the word "and" a lot in these books.  What do you think 
that means???")
