She Apparated into the dark alley. It had been a long day of failed arrest attempts; countless reports of sighted Death Eaters that led to nothing. She heard footsteps behind her as soon as she appeared. She looked behind her and caught sight of someone moving in the shadows towards her. She turned and went toleave the alley when something heavy hit her on the head. She fell, feeling the pull of someone Disapparating with her as she lost consciousness.
When she came to, she was on a hard floor.
"Little Nymphie, it's great of you to come back to us." Bellatrix taunted. "We're going to have fun, aren't we, niece?"
"What do you want?" She asked.
"We need you to help us get that werewolf to come to us. He'd be awfully useful, since he could get into the Order and kill from within." Bellatrix said. "On second thought, you both could be useful. We'll use you to get him here. Then we'll use both of you. Oh, but why am I telling you this? I want you to bring him to me."
"I won't do anything for you." Tonks snapped.
"Oh, won't you?" Bellatrix asked. "Imperio."
Tonks' mind went fuzzy.
"You're going to the Order. You're going to bring Remus Lupin here to me. Kill any Order members who cross you. You will not tell anyone about what I've told you." Bellatrix said.
She stumbled into Grimmauld Place, avoiding the umbrella stand.
"Nymph, where have you been?" Sirius asked, appearing in the door. "Are you okay? You're head's bleeding-"
"Fine. I'm fine." She said.
"Dora, your eyes are all glazed. What happened?" Sirius asked, leading her to the sitting room and making her sit. "Molly!"
"Sirius, I'm busy dealing with the twins. What do you want?" Molly asked, appearing in the door.
"Something's happened with Dora. It looks like someone hit her on the head and she's bleeding." Sirius said, kneeling in front of Tonks.
"Sirius, you know Healing spells!" Molly said, pushing Sirius out of the way. "Why are her eyes glazed?"
"I'm fine. It's just a small cut." Tonks said.
Molly shook her head and accioed a rag. She wiped the blood away and cast a Healing spell. Tonks pushed Molly away and stood.
"Where's Remus? I want to talk to Remus." She said.
"He's upstairs in his room." Sirius said. "Nymphadora, you should lay down. You must have been hit on the head hard."
Tonks shook her head. "I'm fine." She said, leaving the room.
Emmeline was just leaving the kitchen and bumped Tonks. "Oh, Tonks. I'm sorry!" She said. "Are you okay? Why do you look-" Emmeline stopped talking.
"I'm fine, Emmeline." Tonks said.
"Are you sure?" Emmeline asked. "You look like you've been Imperiused-"
"Of course not." Tonks said.
"Alright then." Emmeline said. "I'll see you tomorrow."
Tonks watched Emmeline walk out of Grimmauld Place. She disappeared upstairs, towards Remus' room.
She knocked lightly. "Remus?" She called.
"Mhm?" Came Remus' reply.
Tonks pushed the door open. "Want to take a walk with me?"
"I'm tired, Nymphadora. Full Moon's tonight. How about one tomorrow?" Remus offered. "I'd love to walk in the morning."
"Alright." Tonks said, smiling and shutting the door.
She walked back to her room, waiting until Remus was up in the attic with Sirius and after everyone was sleeping. She crept downstairs and to the kitchen. She grabbed a knife and went outside. She disapparated to Emmeline's house. Emmeline knew. Just by the way she looked at Tonks. She knew.
Tonks blew the door of it's hinges. She strode to the bedroom as Emmeline opened the door, her wand out. Tonks threw the knife, watching it sink into Emmeline's chest.
She walked up to Emmeline after she fell and pulled the knife out. Emmeline whimpered as Tonks leaned over her. Tonks dragged the knife swiftly across Emmeline's throat and stood.
She Disapparated, appearing right outside Grimmauld Place once more.
She went into the house and went to go straight to the kitchen. She froze when she saw Kingsley at the table.
"Tonks, is that you?" Kingsley's voice asked from the table. "Where were you? Why do you have that knife?"
