It took some time before Harry was able to move himself out of the castle. Hogwarts provided a safe place for both he and Ana to stay until Grimmauld place was clean, at long last. While Hermione and Ron saw to that, and Minerva and Harry saw to setting the school back to rights, Ana rested and recuperated quite well under the watchful eye of the headmaster painting of Dumbledore temporarily moved into Harry's old room. The painting Albus, Ana and Harry debated for long hours on why Voldemort's attack on Ana had not killed her. Dumbledore was finally able to surmise two reasons, either of which could have saved Ana's life, though more likely both had a hand. The first was the idea that Voldemort appeared to have tried to not only use Ana's wand against her, but also to imperious her by touching her hand alone and making her kill herself. Historically those who tried to kill themselves that way rarely succeeded, the number of the opposite effect of successful suicide numbering only in the tens over hundreds of years. And that was with people who wanted to die.
The second cause, and more likely to be the actual perpetrator, was that Ana was, in fact, very much like her mother. And Voldemort was, in definite fact, in love with Natalia Weasley for some time before and after she left him. As Bellatrix had told Harry once, you have to mean an unforgivable curse. Otherwise they do very little harm indeed. with the likeness of the only woman Voldemort had ever loved, or was capable of loving, before him, it was unlikely the things he said by way of claiming to loathe Natalia probably were as far from the truth as you could get. Therefore, he could no easier kill Ana than he could have killed Natalia. Likely that was why he made sure Natalia had been imprisoned years before: killing her simply would not have worked.
As for Ana's voice, it was as short lived as Voldemort had described. By the morning following the battle it was gone again and she and Harry were back to their publically private conversations. Harry had the feeling Ana liked that better anyway. After a week of recouping and much restoration both the school and Number 12 were ready to reopen their doors as properly looked after buildings, though Minerva made certain Harry knew he was welcome for tea and biscuits in her new office anytime. Harry and Ana returned to Grimmault place, thinking they would be living with Ron and Hermione for awhile, but it turned out they found the solace of the Burrow more comfortable. Ron had been gone a long time and Hermione had nowhere to go to. And anyway, Molly would want all her children close following the loss of Fred.
So there they were, Harry and Ana alone in the big house. When they arrived the drawing room, three bedrooms, kitchen, library and all the bathrooms had been cleaned, even renovated some and Kreacher had returned, setting to work removing the old pictures from the walls along with a few straggling house elf heads. Judging from the pungent fumes of Doxycide, it appeared Molly had helped Ron and Hermione in their quest to finish the house.
But it wouldn't always be a lonely space. While Tonk's parents had taken on caring for Teddy the rascal was bound to be visiting often, and then with Kreacher being more pleasant than their previous stays coexisting with him, there was always someone around to chat with. They let him have the bedroom at the top of the stairs, Sirius' mum's old room. It made him happy enough, and without seeing as many people come and go, Mrs. Black had very little to shriek about these days (that painting would not be possible to dismantle until someone created a charm to undo whatever she did. Maybe someday, Harry mused.)
With the battle behind them and the world adjusting back to its previous existence before the return of the most dangerous wizard that ever walked the earth, that left Harry and Ana with some choices to make. Neither had finished school, but Kingsley was quick to offer them places in the auror's office, citing the desperate need for some new, trustworthy, people. Ana was concerned about her lack of voice, but Kingsley reassured her that aurors typically worked in pairs and as long as Harry and Ana worked as a duo there would be no problem.
They agreed to the arrangements, particularly when Bill had stuck his neck out for Ana a couple years before based on her O.W.L. scores, but requested they take some time first. Ana thought they would spend a week or two relaxing at home. Harry had a different idea. He presented Ana with a picture of an ocean side cottage on the coast somewhere that night at dinner. 'It's lovely' Ana signed, 'but what's so special about that place?'
"It just seems perfect."
'For what?'
"To start over. To break away from the old for awhile and just start things new."
Ana could hardly argue with that.
