ooc: It's the same as in GoF, they can go if a date escorts them (Ginny could go because she went with Neville).

"Morning" I smiled as Stevie and Kira sat opposite me. They where both looking rather tired.
"B's going with a Slytherin" Kira said osunding rather sad about it. I looked up over 'Charming through your fifth year' (a rather thick chamrs book) and said vaugley.
"Yes, I guess she would" Kira and Stevie exchanged looks. I rolled my eyes "Well...you would expect a girl like her to be attracted to the rebels"
"What?" Kira asked "Why would we expect that?"
"Because that's what she knows of her father, he was a rebel and she has always wanted him there...it's natural for her to want someone like her father" I smiled. Stevie looked between me and Kira,
"Well...I suppose you two both don't have dates now, so maybe you should-" She was cut off.
"What? I have date" I said defensivly.
