"They took Teddy, and then simply returned him?" Remus asked, frowning. He looked down at Teddy, who currently had Remus' light hair(grey included) and light eyes.

"We asked Lucius, who admitted to being the one who returned Teddy, and he won't tell us why. He just told us that Narcissa took Teddy from the Death Eaters who had kidnapped him, and urged him to return Teddy to us. And that's all we know." Harry explained. "It helped their cases, honestly, when they said they were defected from the Death Eaters- and the fact they helped return a child of Order members- I mean, it definitely helped their claims."

"So, the Malfoys aren't in Azkaban?"

"Lucius served 40 days- all of August and part of September. Narcissa wasn't arrested at all, and neither was Draco. Draco is actually back at Hogwarts- apparently he's getting his NEWTs to become a Healer."

"And Dora- you haven't told me- how did she die?"

"We're not sure." Harry said slowly. "Like I said yesterday, we just found the house trashed, found her wand broken, her blood was everywhere. Never found her body."

Remus sighed deeply. "And you're sure she's-"

"Remus, I wish I could say no, I really do."

"Are you alright?" Harry asked. She kind of looked like she was about to be sick, and had dropped her head into her hands.

"I cheated on Remus! I thought it was bad enough when I thought him dead, but somehow, it's worse now- he's alive, he's been alive this entire time and I slept with the werewolf that turned him into a werewolf!" She cried. "I was just- I just wanted information about Teddy, I really didn't mean to sleep with Greyback but he wasn't- he wasn't handing over information very easily, I-"

"Tonks, calm down. I won't tell Remus." Harry said. "I won't even tell him you're alive, if that's what you'd prefer."

"No, he deserves to know." She said, finally raising her head. "Even if you do put me in Azkaban-"

"There's going to be a trial, Tonks, I hope you know that." Harry explained. "There is a chance you'll get sent to Azkaban, but as far as I've seen in the courtroom, people are being acquitted- if there's no proof of them being Death Eaters willingly or if the attacks they might have been part of were self-defense, or forced. However, I'm not promising anything for you- these were brutal killings, Tonks. You have clear scars from your encounter with Greyback, which could have been proof of a self-defense motive during that killing, but you've also admitted you went to him. It'll probably be a difficult case for the Wizengamot to face- you were an Auror, an Order member, and now you're facing murder charges. And Kingsley- as the Minister- is going to have to oversee the entire thing. The only thing that might help you now is if you tell every single detail about the last three years to them."

"To the entire Wizengamot?"

Harry nodded. "Now, Rookwood was killed in December of 1999." Harry said. "Where were you between January and December?"

"I was trying to find Rookwood."

"And after you found him, what was the meeting like?" Harry asked. "Why did you kill him?"

"He was a Death Eater."

"A Death Eater that told you that Teddy was back with the Order." Harry said. "Why did you kill him?"

December 7th, 1999

She followed Rookwood through Ottery St Catchpole. It seemed interesting that this Death Eater, who was being actively searched for, was hiding in plain sight. He had transfigured his features and it took a while for her to realise it was him, but once she figured it out, she followed him.

She cornered him between two shops, not bothering to morph.

"You probably know exactly what I want." She said. He spun, raising his wand immediately. "Expelliarmus!"

She caught his wand, and she pressed hers against his throat, shoving him against the wall.

"I don't have your son." Rookwood growled.

"Where is he?"

"How would I know?"

"Were you the one who took him?" She demanded.

"I was among them."

"Them? Who's them?"

Rookwood looked down at her, not saying a word.

"Tell me!" She demanded, pressing the wand harder. He raised his hands, grabbing for her hands, and she threw her knee upwards, catching him between his legs. He fell to the ground, swearing, and she shoved him onto his back, pressing the wand against his throat again, straddling his chest. "You better give me answers, Rookwood."

"I had him for two days!" Rookwood snapped. "That's all!"

"And after the two days?" She demanded.

"I- Rabastan Lestrange took him."

"Where did Rabastan take him?"

"I don't know, why would I care?"

"You better start caring." She spat. "Where's Rabastan?"

"Last I heard he was arrested."

"Bullshit." She said, pressing the wand harder. "Where is he? Or am I going to have to use the Cruciatus on you?"

"Glasgow! That's what I heard!"

"Are you scared of a little pain, Rookwood?" She asked innocently. "How do you think the Muggles felt? Or the Muggle borns?"

Rookwood tried to push her off, but she leaned over, pressing a forearm against his throat, moving her wand to his forehead.

"You know who else fought?" He said, when she lifted her arm slightly. "Your father, the filthy Mudblood-"

"Avada Kedavra!" She cried, her wand pressed against his temple. There was a quick flash of green, and his eyes became unfocused instantly, his body becoming limp beneath her.
