He jumped to her side and quickly put a shield up around them. Teddy stroked her face and whispered to her, begging her to stay strong. He dragged her body to the side in between some trees and put an invisible wall around her. He turned to face Sagitta and watched as she spit on the ground in front of him.
"Now that the blood traitor is out of the way, I can kill you." She sent another round of the Cruciatus Curse at him and this time, he felt a burning weight buckle his knees. Every muscle in his body felt like it was on fire, and his head was filling with such intense pressure that it felt like it was about to explode. When he gained control of his body, he shot out a weak disarming jinx. It didn't do much, but it did cause Sagitta to drop her wand to her feet. Teddy took action and put her in a body bind.
It worked for only twenty seconds or so since Teddy was still in pain and couldn't focus properly. As soon as he caught his breath, Sagitta rose to her feet and picked up her wand. "You think you can defeat me that easily?" she cackled. "I've got more than that in me, you'll soon see that." She screeched out the Killing Curse as her wild eyes searched Teddy's. He heard the words come from her mouth, and as the green light built from her wand he ducked and fell face first on the ground. For a moment, he thought he was dead. His body was tight and his muscles refused to move. He heard the evil witch laugh loudly. 'I'm alive,' he thought. 'I'm alive and she thinks she won.' She paced back and forth, still cackling. Teddy suddenly lifted his wrist and stupefied her with powerful force, sending her flying thirty feet backwards. He jumped up and raced to pick up her wand. He snapped it in half with his knee and put Sagitta in invisible ropes. She screamed curses at him, but without her wand, it was hopeless. He knocked her unconscious and made sure she was asleep. He sent up red sparks and sent his Patronus up to the castle.
He ran over to Victoire, disarming the protective wall. He felt a lump rise in his throat as her limp neck rolled in his arms as he lifted her head and shoulders. "Victoire? Please wake up, Vi. I need you. Please wake up." Teddy turned his head when he heard shouting and footsteps.
"TEDDY!" Professor McGonnagall, Liam, Lily, and Hagrid came to his side. "Oh Merlin, what happened?" McGonnagall asked. Teddy explained Bellatrix's daughter wanting to get him out of Hogwarts so she could kill him, and her plans using a teacher and a student to slip notes and manipulate Victoire. He told them of how he heard Victoire scream so he ran to find her, and she was Cruciated and passed out. How he was also tortured, but he regained his strength and knocked Sagitta unconscious. All this he explained on the way to the hospital wing. Hagrid was carrying Sagitta, while Liam and Teddy carried Victoire.
"So you don't know how she got into the Forbidden Forest in the first place?" McGonnagall asked worriedly. Teddy shook his head.
"And I don't know what she was doing fighting Victoire, either." They all silently turned their gazes to the sleeping Gryffindor girl. Madam Pomfrey asked everyone but Teddy and the headmistress to leave. Hagrid brought Sagitta Lestrange to McGonnagall's office and held onto her so she wouldn't escape. Teddy held onto Victoire's hand as McGonnagall asked him some more questions. He tried to answer them the best her could, but he couldn't shake the slightest hint of the burning feeling in his chest and his knees. "I'm sorry Professor, but may I interrupt you for a minute?" he asked warily.
"But of course, Mr. Lupin. Considering what you just went through you may have whatever you wish."
"Thank you. Madam Pomfrey, can I please have something to get rid of the effects of the Cruciatus Curse? I still feel it." The nurse bit her lip and nodded. She handed him a bottle of green liquid that smelled awful and pointed at a cot next to Victoire's.
"Please drink that entire bottle and lie down on the cot. I'm afraid I'm going to have to keep you here for a while longer. I'm sorry Headmistress McGonnagall, but the curse was much more powerful than I expected. We'll need him to stay." McGonnagall nodded solemnly and smiled at Teddy.
"You'll feel better soon, Mr. Lupin. I know you will." She excused herself and headed for her office. Teddy looked nervously at the bottle and gulped it all down. He gagged a bit and then drank some water. He lied down on the cot and closed his eyes.
