"Tonks, is that you?" Kingsley's voice asked from the table. "Where were you? Why do you have that knife?"
Tonks stared at Kingsley, holding the knife behind her. "Kingsley, what are you doing down here?"
"Having tea." Kingsley said. "Are you alright? Why do you have a knife?" He asked again.
Tonks pulled out her wand. "Obliviate." She said.
She cleaned the blood off of the knife and her hands and replaced the knife. She slipped upstairs, ignoring Kingsley who was still at the table.
The next morning, she woke up before the sun had risen. She went downstairs, waiting for the sun to rise so she could get to Remus.
Kingsley was downstairs as well, looking over a piece of parchment. He looked up as she entered the room.
"Tonks, I've been meaning to talk to you. Yesterday, Sirius said he was worried about you-"
Tonks pulled out her wand and Stunned him. He was thrown backwards, crashing into a bookshelf. Tonks disappeared back upstairs. A few seconds later, she heard footsteps going down the stairs and some talking.
Tonks made her way back downstairs a few moments later.
"What happened here?" Tonks asked.
"We don't know." Arthur said. "Alastor and I will take Kingsley to St Mungo's and maybe they'll know."
While Arthur and Mad-Eye took Kingsley, Tonks wandered over to Remus.
"Want to take a walk now?" Tonks asked.
"The air will be nice." Remus said. "Let's go."
Sirius watched as they walked out of the house. He stood at the window, watching them walk. They got a little way from the house, and Sirius watched as Tonks drew her wand on Remus and cursed him. A second later, she grabbed Remus and Disapparated with him.
Sirius' heart faltered. What had gotten into Tonks? As soon as Arthur and Mad-Eye returned, Sirius went to them and explained what he had seen.
As Remus began to wake up, he felt a sharp pain in his left temple. The last thing he remembered was Tonks drawing her wand and hitting him.
"Remus, oh. Remus, I am so sorry-" Tonks stammered, moving closer to him.
"Dora, stop." Remus said, sitting up. "What happened?"
"Bellatrix. She Imperiused me and I can't remember much, but I remember hitting you. And I'm so sorry!"
"Dora, stop." Remus said, facing her. "Where are we now?"
"I don't know. She must have removed the Imperius after she brought us here. I don't know where we are." Tonks said. "Oh, it's my fault. I should have fought the Imperius-"
"You couldn't have. Calm down." Remus said. "Panicking won't help anything."
Bellatrix entered at that moment. "Greyback, take the girl." She said. "I want to speak with the mutt."
Greyback grabbed Tonks. She fought him as he dragged her out.
Bellatrix leaned to eye level of Remus. "I want you to join the Death eaters." She said. "We hate that you're too human to murder, but we want to change that. We need werewolves."
"I'll never join you." Remus growled.
"Greyback!" Bellatrix yelled. "We need to convince him!"
A few seconds later, Remus heard Tonks scream.
"No, stop. Stop hurting her!" Remus begged.
"Greyback, stop!" Bellatrix called. Tonks' screaming ceased.
"So, will you join us?" Bellatrix asked.
"No." Remus said.
"Very well." Bellatrix said. "Greyback, bring the brat back in here. We'll leave them for a while."
Greyback dragged Tonks back in and threw her down near Bellatrix. They disappeared together a second later, leaving Remus and Tonks.
"Are you okay?" Remus asked. "What did he do?"
"Bit me." Tonks said, showing him her arm. "It won't do anything, will it?"
"What would it do?" Remus asked. "Turn you into a werewolf? It won't turn you. He wasn't in wolf form."
"What are we going to do?" She asked.
"I have no clue." Remus said.
"I don't believe she actually had anything to do with it." Arthur said.
"I saw her! She attacked him!" Sirius said.
"I think she was Imperiused." Kingsley said. "She was acting weird. And you said you saw her eyes were glazed."
He had been back at Grimmauld for 2 days now, and Tonks and Lupin had disappeared almost 5 days before with no clues whatsoever about where they could be.
"So we need to find them." Mad-Eye said.
"That much is obvious, Alastor. We have no way of finding them, however." Bill said.
"We'll have to find a way." Mad-Eye said.
