Cafi walked rapidly down the aisle, running her finger along the spines of the books. She had in her robe that strange potion which she had received in the mail after her birthday. It looked pretty much like water, only a little thicker. She hadn't dared uncork it. She didn't know why, but it had come with no instructions on how to use it or what it was. That was the reason for her being in the library. There was an itching desire in her to know what it was, what it was sent to her for, and why whoever sent it was so secretive. She had spent the summer at a relatives place, because her parents were in Rome, and had not been able to reach a library the whole time she was there. Since she had gotten back, she had spent an hour every day searching the library for some clue as to what this little vile contained. So far, she had not found much, only short sections where clear potions were mentioned, but not enough to work with. Now, as she scanned the aisle, one name stood out to her.
'Potions and their Uses.
A general guide to most of the known potions,'
Was it's label. Reaching out, Cafi pulled the book down off it's shelf and walked with it over to a table. As she sat down in a chair with her book in hand, she heard someone coming.

Ugh! I hate charms . . .
Tell me something I don't know. But it's getting a bit easier here . . .we've moved onto Non-verbal charms . . .
Well, isn't that just lucky for you?
Chin up Brother . . . this next plan will get us back together in no time . . . At least, the two hoped it would. Their last plan had not worked to get them kicked out of school. Mainly because they hadn't been caught! That was why they met in London . . .just so they could divise yet another plan.

Vincent plucked the Hogwarts: A History out of the book shelf and opened it to a random page. He read what was on that page before randomly flipping to another. Nothing of interest there. At least that's what he had noticed.

He moved along towards the Charms section (As that was why he was in the library). He was supposed to be doing some research project on a particular charm. Sitting at a table, he plopped the book down not realizing someone was already at that table. His gaze drifted to hers and he bit his lip. He gave Cafi a small wave.

Cafi looked up at the sound of the book hitting the table. She was a little surprised to find that it was Vince sitting there, as this was where they had met the last time.
He waved. She remembered that he hadn't been much of a person for words.
Unfortunately for Vince, that wasn't how it was with her.
"Hey Vince." She said, smiling at him.
She thought of their last encounter and laughed.
"You haven't been spying on me have you?" She asked jokingly, giving him a wary eye. She had forgiven him already for last time, though she still remembered it clearly. She pushed her chair closer to the table and felt the vile of potion bump into her leg from inside the pocket of her robe. That reminded her what she was here to do. She flipped quickly through the book. She was pleased to find that it was illustrated, which would be great for finding out if her potion matched to any in the book. A picture caught her eye. It was just an empty potion bottle. Or so it seemed at first, but after looking more closely, she came to the conclusion that the bottle had some sort of liquid in it. This was exactly what she had been looking for.
She prepared to read on, but was distracted by Vincent's reply.
