The sound of the train on the rails was the only thing disturbing the silence of their compartment. The two students were lost to the world as they rode aboard the Express as it whisked them back to the Muggle world for the next six weeks*. Harry Potter was doing all he could to focus on his bushy-haired girlfriend who was snuggled up next to him, and to not focus on the anxiety he felt over spending so much time in the 'care' of his aunt and uncle.
In all fairness, Hermione was doing an extremely good job of distracting him from his troubles. She had latched onto his side five minutes before and had refused to let go since, the gift he had given her that had sparked the impromptu cuddle time gripped tightly in her hand. The gift in question was a tartan hairband and a small cloth bag. Not much to look at on their own, but then that was the point. They needed to look normal so that no one would pay attention to them.
It had started last Christmas; it had been a rather simple plot to use Polyjuice potion to sneak into the Slytherin common room and find out who was targeting the Muggle-born students, before they killed someone or worse, got Hermione. It just went to show that even simple plans can go very wrong. They were unable to learn who was attacking students, unable to stop the attacks and worst of all, Hermione ended up petrified anyway. Oh, and thanks to a mishap with Hermione's potion his then friend, now girlfriend, was stuck with cat features.
It wasn't as bad as it could have been. At first, she had looked a lot more like a cat, but Madam Pomfrey, while being unable to reverse the effect entirely, had managed to restore most of Hermione's original, human features. She now only spotted cat ears and a tail, as well as a patch of fur that ran along her spine from the middle of her back down to her tail. The rest of her was back to normal, on the outside at least.
Harry didn't know all the details, but there had been some subtle, and some not-so-subtle, changes in his Hermione. A lot of it was easy to explain and dismiss, such as Hermione's preferred foods having shifted a bit. She doesn't dislike anything more than before but her fondness for fish, chicken and milk had gone up exponentially. Harry had noticed this, as before taking the potion, Hermione tended towards porridge and pumpkin juice for breakfast, but now she was beginning to alternate between that and kippers on toast* with a goblet of milk.
She also seemed to understand cats better. She couldn't talk to them like Harry could with snakes, but she seemed to be able to know what they wanted whenever they were around her. As such she had become quite popular with the cats in the Gryffindor tower. Hermione was also more of a hugger now. A lot more. Well, not so much more of a hugger than a longer hugger. At least with Harry. But then he was unsure if that one was a result of some cat instinct to snuggle into anything warm, or just a perk of their upgraded relationship. Either way, he wasn't complaining.
There were also the potions she now had to take regularly that she refused to tell him about, only saying that it was private and wasn't a problem. He had stopped asking after that but couldn't help but worry for her.
His worry had been one of the reasons behind the gifts. While they did nothing about whatever problem was leading to Hermione needing to visit the hospital wing every few weeks, it would help with her life outside of school and let Harry feel like he was doing something. The real gift had been the three small cloth bags, two of which were concealed in a tartan hair band. Each of the bags had an undetectable expansion charm on them. This meant that while wearing the hair band Hermione could easily and, most importantly, comfortably hide her cat ears even in the Muggle world. The third bag was loose and was to conceal her tail. With her gift and a few simple fashion choices, Hermione would hopefully be able to pass as normal in the muggle world, and not be stuck in her house for the whole summer hiding from everyone but her parents.
The compartment door opened, revealing the two youngest redheaded Weasleys. Ron and Ginny had barely been seen without each other since Ron and Harry had retrieved her from the Chamber of Secrets. The youngest Weasley had understandably latched on to her brother for support after everything that had happened to her, and after his fear of losing her that day, Ron was more than happy to be there for her.
If it hadn't been for Ron's reaction to Hermione's current appearance, the couple would have been happy to see them. As it was though the echoes of Ron's bullying of Hermione's feline attributes had had a huge strain on the friendship of the three. Harry and Ron had both stuck by Hermione in the beginning, but after two days Ron and Hermione's regular bickering had started back up. It wouldn't have been too bad but Ron had taken it too far, as per usual. He'd started making cat-based insults towards Hermione. This had gotten her so upset that Madam Pomfrey had banned Ron from the hospital wing.
That would have been the end of it but when Hermione was released from the hospital wing two weeks later the three were informed by Professor McGonagall that for brewing an illegal potion the three would be spending the next six Saturdays with her in detention. Ron had started complaining loudly to anyone who would listen, claiming that it was Hermione's fault that the three of them had gotten the stack of detentions, and then for Gryffindor losing the Quidditch cup because one of the detentions was the day of the match, leaving Harry unable to play.
