The Potter and Black boys were still giving Snape a hard time but he found it more easy to ignore it than he had first assumed when she was with him.One thing you must understand about Katrice is that she is a very loud person and also that she had never been afraid of speaking her mind.Any time these boys would tease Snape they got a load of her mind. She was deffinatly not the one to mess with.

She had also held true to her promise of teaching him potions and once he had gotten the ingredients from the dungeons he was very glad indeed the he had.She knew all sorts of things about them. It aslo came to pass that he became very good at making them.Following directions was the only tool required and this tool he had been blessed with since birth.They were the potions teacher's fravorite students though I suspect this would have beeen different had he known that they had been practicing their potions with his stolen ingredients.But, he did not know and so he liked them very much.

As of yet they had had no oppertunity to test ant of their potions on a human being.This soon changed for one day after flying lessons Sirius Black had insulted the "relationship" between Sirius and Katrice.This would not have bugged Severus if he had merely said that they were a couple but,in fact, Sirius had said not only this but had offered Katrice a more suitable boyfriend (himself).This enraged Severus.It was as though Black were saying he were a better person than him. Katrice glared at him.This usually worked as her eyes could bore a hole through anyone if the tried hard enough. But before Serius could back off Snape lunged at him. Katrice grinned but quickley pulled her friend away from Black.The unfortunate consequence of this encounter was the their flying instructer had seen only the end of it where Severus had pounced and gave him,and him alone, a detention in which he was to clean toilets but the up side was that Katrice now found that thay had their potion "Guinea Pig"

So it was that three days after the fight a few drops of swelling potion found its way into Sirius Black's drink. How did it get there you might ask. This is how.Under the pretence of complaining about his treatment of her friend Katrice had gone over to the Gryffindor table during dinner. Black made the mistake of looking into her eyes. The result was that he sucked in her every word. When she had made to stand up she pretended to slip and in an attenpt to catch herself fung her hand out catching his glass rether than the table and nearley knocking it over.In truth she had dropped a disolvable tablet into it.No one noticed. She then rejoined Severus a grinn set firmley across her face.Sirius had gone back to speaking with his friends:James,Remus,and Peter.

Oh how the hall bursted out when Sirius' face began to stretch and his body expand.people on either side of him had to stand up to allow him room.Girls were shrieking(For they Found Sirius very charming)Severus and Katrice were full out laughing.

"It really works!"Said Katrice triumphantly,clapping hands with Severus and then giving him a hug.

This waas just phase one in the overall sequence of events which the pair set off during their years at school together.
