Because I am too obsessed with AUs.
...
They were standing silently, wands ready. Harry and Tonks were shoulder to shoulder, their backs pressed against a wall. Dean and Seamus were in a different part of the abandoned and secluded house, but at the sound of a yell and thud from the floor above them, Tonks knew this wasn't going to end well.
"Do you trust me, Potter?" She asked quietly, closing her eyes and taking a deep breath.
"Yes?" He responded, even though he didn't sound like he trusted her in the slightest.
"Good." She said. She reached to his hand, prying his wand from his grip and pocketing it. She turned before he could speak, quickly Transfiguring his hair blonde and his eyes a dark brown. She grabbed his glasses, duplicating them and tapping her wand against his pair to change the shape slightly. She slipped off her wedding ring, shoving it into her pocket.
"Tonks, what are you-"
"Shh!" She demanded, handing him back his glasses. She morphed to become Harry Potter herself, shoving on the duplicated pair of glasses. "Scar?" She asked.
"Yes-" Harry said, his eyes darting to her forehead.
She reached up, pointing her wand against his forehead, muttering a concealing charm so his scar would vanish temporarily. "Ring." She said, pointing to his hand. She quickly waved a wand over her robes and boots so that her version of Harry Potter wasn't wearing women's robes. She took Harry's wedding ring, putting it on and shoved her own wand into Harry's hand.
"I saw at least ten of them." She said, and Harry was a little stunned that he was currently talking to himself- voice and all. Tonks had always amazed him with her ability to mock voices as well as looks, even though she had admitted she couldn't morph a voice. "We'd be stupid to fight. We go out there, and if we're outnumbered, do not fight. We'll find our own way out later."
"And this-?" Harry asked, gesturing to her and her flawless disguise. Harry was searching her- his - features for some sort of give away, but the only thing he noticed was a freckle on her- his - cheekbone that the real Harry didn't have.
"You're still the Boy Who Lived, Harry." She said.
"We know there are two more of you." A harsh voice said as footsteps came pounding into the room behind them. "We got your friends, so unless you want them dead-"
"Stay here." Tonks said, stepping around the wall to face the voice. "Amycus Carrow." She said, her voice still matching Harry's. "You look like shit."
"Crucio!"
The wall Harry was leaning on shook at the force of the spell- clearly Tonks had managed to avoid it.
"Well, well, Potter." Another voice said. "It's a pleasure."
There was a sickening crunch and Harry heard his counterpart gasp painfully. He rushed around the wall, aiming Tonks' wand- knowing his spells would not be very effective because he hadn't won her wand. Harry was shaken by the sight of himself being propped between the Carrow twins, blood pouring down his face.
"Gregors." Tonks managed. "I told you I'd handle it."
"Expelliarmus!" Alecto cried, effectively catching Tonks' wand when it flew from Harry's hand. Catching her- his- eye, it was obvious she had diverted his attention for a split second on purpose. Working together for ten years, she knew exactly how he would react in these situations- and she was right to stop it, because he would have definitely tried to duel them and that would have probably ended badly.
"Incarceous!" Alecto cried, and Harry felt himself get wrapped in tight ropes. Two pairs of arms grabbed him from behind and he felt a wand press against the back of his neck and a series of muttered words and the world went dark.
Harry woke up on a chair, his arms still tightly bound. He looked around and saw the other three were also bound to chairs beside him. Tonks was still maintaining the morph, and Harry had to be impressed. Her nose- technically his- had been bleeding very heavily and he was amazed she had kept the morph when the Death Eater had broken it.
A door opened and Harry could hear footsteps descending stairs behind them. A dirty mirror in the corner in front of Harry allowed him to see the black robes before they stepped in front of him.
"So we got Potter, but who are the others?" An unfamiliar voice asked.
"Seamus Finnigan, Dean Thomas." Alecto said. "Never saw the blonde before, but Potter said 'Gregors', so I'll assume that's his name."
The figures stood in front of them, facing them. Harry only recognised the Carrows, he had no idea who the other six were. He looked towards Tonks, hoping maybe he'd be able to tell if she knew them based on her facial expression, but her face was clear of any emotion and unreadable.
"So, Potter." Amycus said, and Harry expected him to be facing him, but then remembered- he wasn't Harry anymore. "How would it feel if we were to kill you now, and leave your body in Diagon Alley?"
"The dead can't feel, Amycus." Tonks responded, and Harry's eyes widened. He had said his share of witty remarks, but he wasn't sure if this was a stupid or incredibly smart move on Tonks' part.
Amycus raised his wand, aiming it at Tonks. "Crucio!"
The second the spell hit, the morph dropped and Tonks' scream filled the small room as she writhed against the ropes. Amycus lifted the spell, apparently confused. Tonks slumped forward, her body shaking.
"What the-" Alecto said behind her brother. "So they still protect Potter, do they? Well, Auror Lupin, where's Potter?"
Tonks didn't answer, and Amycus grabbed a handful of her hair, pulling her head up. He leaned close to her, pointing his wand at her throat. "I'd suggest answering, or I will kill you."
Tonks still didn't answer. Instead, she did something that shocked Harry even further- she spit in his face. Amycus stepped back, wiping his face. When he looked back at Tonks, he looked murderous.
"Kill her." He said. "Leave her in Diagon Alley."
Harry's eyes widened as Alecto stepped forward.
"No!" He yelled as Alecto raised her wand at Tonks. The Death Eaters turned to look at him, and he spoke quickly, because he could see his hair darkening again in the reflection of the mirror- the transfiguration was wearing off finally. "I'm Harry Potter."
