For Sophie
Teddy had always been an important person in Lily's life, they had such a strong bond that Lily had even referred to him as her third brother. The first person she had written to after being sorted was Teddy, her letter to him had been longer and more in depth than the one she had sent her parents. He had written back with a letter just as long.
It was like that all through her Hogwarts years. Lily would always write to Teddy first about anything that happened. When she started struggling in Charms and Potions, her worries about trying out for the Quidditch team, her first crush, first date, even her first kiss. Teddy had known about all of them and more before her parents had.
He had been the first to know about her plans to travel after Graduation, he wrote back, trying to convince her not to go alone. But as stubborn as ever she hadn't listened. Lily had set off with excitement and adventure in her eyes.
For the first year the letters sent by Lily were long, full of stories and numerous. Each letter brought comfort not only to Teddy, but her parents and brothers. But as the second year progressed and Lily's travels continued, Teddy received fewer and fewer letters from her until they eventually stopped coming.
He still wrote to her every week, waiting and hoping for a reply but it never came. Eventually, albeit reluctantly, Teddy stopped writing to Lily as well. He kept the letters she had sent him throughout Hogwarts and prayed that she wherever she was she was safe.
