Whilst buying their school supplies, they had stopped in the Weasleys' Wizard Wheezes store owned by Fred and George. Hermione saw a lot of very advanced magic in some of their products, not only in potions, but in transfiguration and charms as well. When she saw the boys pointed out that they could have done so much better in their O.W.L.s.
"Well you know us, 'Mione. We're not that into the 'learning stuff by heart'. We like experimenting better," said George, swinging an arm around her shoulders.
"Come on Harry, we want to give you a special tour!" said Fred.
"' 'Mione, look what I found," said Ron, handing her a bright yellow telescope. "I think you can see Arion."
"You mean Orion, Ron. Arion was an ancient Greek – OW!" Dropping the telescope, Hermione's hand quickly covered her eye. "It punched me," she said slightly bewildered.
"Oh blimey, are you okay? I'm sorry, Hermione. I didn't know it would do that," Ron apologized immediately.
"Didn't bother to read the description on the box, did you?" She asked snippily.
Still clutching her eye, she walked to the exit to get some space. The store sure was crowded. Outside she could find a mirror, or maybe the window of the shop, to cast a small healing spell assuring her eye would not bruise. Not really seeing all too well with the one eye that was not covered, Hermione bumped into a rather large figure.
"Oh, I'm sorry. I wasn't looking where I was going," Hermione said.
"That you weren't, Miss Granger," the familiar voice of Professor Snape said.
"Professor, I-" Hermione looked up at him with both eyes, her hand falling to her side.
''What happened to your eye?" He asked rather rudely.
"Weasleys' product, sir," she cast her eyes down.
"Well don't you have a wand and a brilliant mind like the other professors seem to think you own? Surely you could heal it, or else at least have the decency to cover it up with a glamour."
"I was just about to do so, sir"
"Yes, whatever. I have places to be, so if you stop your shattering I'm leaving," and with that he turned and started walking.
"See you at Hogwarts, sir," Hermione called after him.
After casting a quick healing spell, Hermione walked back into the store, right in time to leave with the rest of the group.
