The next morning, Remus found himself lying on the floor of his and Tonks's bedroom. He was incredibly sore and there were scratches and cuts on his body. He sat up painfully, minding the cuts, and looked around the room. What had happened last night? His question was answered when his eyes fell upon a limp body in the corner of the room.
"No!" he cried, and, forgetting about his soreness, his cuts, his bruises, moved toward Tonks. She was covered in blood, and there were gashes along her face and body. "No," he breathed as he looked at his wife. This was his fault.
Remus snapped into action. He might still be able to save her. He took Tonks gently in his arms, trying not to make anything worse, and Disapparated to St. Mungo's.
Looking back, when Remus had arrived with Tonks in his arms, he had already been subconsciously thinking of leaving. He knew there would be only one way to prevent this ever happening again, and it was leaving Tonks and never going back. As much as it hurt him to do it, he knew it was for the best.
The Healers took Tonks out of his arms and rushed her into a ward. While waiting to hear if she would make it, Remus wrote her a letter.
Dear Nymphadora,
You can't imagine my thoughts when I saw you lying there, broken and bleeding. I have done what never wanted to do – Ihurt you. And that can never happen again. I took too much for granted. I didn't take the precautions I should have. You mean everything to me, and I can never forgive myself for what I have done to you. You made my life so much better, but I know now what I have to do.
I will regret this forever, but I cannot, in good conscience, continue on with you knowing that I can do something like this.
I will always love you and Teddy,
Remus
Remus stayed at Mungo's long enough to hear that Tonks would be okay. As he left, he handed his letter to a Healer, asking if she would give it to Tonks. Remus walked out of the hospital and walked out of Tonks's life forever.
Molly and Arthur came to visit Tonks the moment they heard what had happened. Tonks was delighted to see Arthur, with his nearly bald head, and Molly, with her graying ginger hair walk into her room.
The first question they asked was: "Where is Remus?" At that, Tonks dissolved into tears and handed the letter to Molly. After Tonks had read the letter, she refused to let go of it, trying to will Remus to come back.
Molly's eyes filled with tears as she read Remus's goodbye letter. She handed the letter to Arthur, and took Tonks into her arms, who was still sobbing uncontrollably. When Molly pulled away, Tonks told her about the dream she'd had.
"Yesterday morning, I had the same dream I always do when Teddy leaves for school. Remus left me in the dream, and I was all alone again. It's just me in the house – no Remus, no Teddy, just me! And it happened!" Tonks half-screamed. "And now I'm here, alone."
"Dora, you're never going to be alone. We're all here for you," said Arthur, standing on the other side of her bed. "We'll get you through this."
