The Girl Named Purple

The Memory

The next day Purple woke up with happiness which turned to curiosity when she discovered Ron and Harry at her feet.  "errr... how did you guys get-?"
"There's no time to explain that." Said Harry.
"What's going on" Said Purple, thinking this was just a prank.
"It's Tom"
" I thought that was over!"
"He's hunting for the memory." The memory was belonged to a professor who left Hogwartz just recently.  It was the memory of the night when Tom decided to turn to the evil side.  The night when he has asked something, and that something led the faith of the entire world.  But no one but Tom himself even knew what it was.  But without knowing what was, Harry would never know how to defeat him.
Everything became silent, Purple's was now very scared.  "So what do we do?"  She said.
"Ron and I believe that it is hidden in the Library of Prophecies.  We'll go and well, do the best we can."
"Harry you know Tom is going to have a bundle of dark wizards with him, you'll barely stand a chance!  Take me with you!" Purple begged.
"You don't have any powers, and after last night it wouldn't be a good idea.'
"Or maybe even a brilliant one!" Said Ron.
"What?"  Said Purple and Harry
"If we send Purple there and she pretends like she is still into him, then that will be enough distraction for you (Harry) to retrieve the philosophy and get out.
"Okay, and how will Purple get out?"  Easy, we'll throw in one of Fred and Georg's foggy balls, that auhta give her enough time to get out.
"Great so it's settled!"
"Guys I'm not too sure about this." Said Purple with uncertainty.
"Come on, it's the only way!" Begged Ron
"It's just risky, I mean what if he tries to, you know."
"Hook up with you?  Last time I checked that wasn't a bad thing!" Ron exclaimed.
"Ron we broke up 2 weeks ago and if you think I enjoyed what happened yesterday you are seriously mistaken!" 
"Oh am I!  Well if you didn't like him kissing you so much then why did you even walk out there with him in the first place!"
Purple looked down.  She didn't know what to say.  She felt ashamed.
" Purple, he didn't mean it, he's just a little upset is all." Harry said sensitively.
"Yeh, honest I didn't.  I'm sorry," Ron realized he had upset her.
Purple simply said "It's fine."  Purple knew she couldn't get mad because she had secretly asked herself the same question.  Why had she gone outside with him?
"Err, so that plans not gonna work, what else should we do?" Said Harry.
"No, it's okay, I'll..." It took a couple seconds for her to say it.  "...  I'll do it."
