"Alex" Lily shouted, trying to get her attention, "Help me with him, we need to get him to dad's…check he's ok…"
"Sure Lils" Alex replied, taking one of Sirius arms and placing it around her shoulder, and Lily did the same. Thinking back, Lily was never able to remember quite how they managed to get Sirius back to her fathers' house, which was still a few streets away. Getting to the house, Lily rang the bell, her hands preoccupied with holding an unconscious Sirius Black upright.
Her father answered the door, with a quizzical look on his face, "Lily? Alex? Who's this?"
"Not now Dad" Lily replied, moving forwards into the hall, "We need to get him sat down, I'll explain in a sec. Just, not now." Her father, knowing when not to mess with Lily, moved aside and let her pass into the living room, where Sirius was deposited on the sofa.
"Alex, honey, can you get me some water please?" Lily's father asked. After all, he was a doctor, and he knew what he was doing. "We should wake him up, and check for ID"
"Yeah, and no need" Lily replied, without looking at him. She immediately started to tap his face, trying to get a response, "Sirius, Sirius? Can you hear me? Wake up you big loaf!" Sirius started to stir.
"LILY!"
"What? It woke him up?" Lily said, with a smile playing at her lips, torn between worry, and amusement.
Sirius was mumbling now…
"James? Mrs Potter?"
"No, it's not any of them…" Lily's dad replied, not knowing who any of these people were.
"Father? Sir? I'm sorry! Sir. I meant Sir…" Sirius was saying frantically.
"No! No Sirius it's not your father. It's Lily, Lily Evans. You know from Hogwarts." Ignoring the quizzical look from her father at what she was saying to the boy she carried on, "You remember, we're both in Griffindor. Come on, wake up. Look at me." When that failed she thought of something else she could try, "Look at me…we have hot chocolate? No? Fine, open your eyes and look at me or I'll slap you!"
"LILY! Don't talk to someone like tha-" But he stopped short. Sirius' eyes had snapped open, and Alex was laughing like crazy, having come out of the kitchen with a glass full of water.
"That's better, now, dad's gonna take care of you. I have to go do something." With a meaningful look to her father she headed upstairs, into her bedroom, and got out a quill and some parchment, and began to write.
James,
