"Well.. you'll always be my brother as far as I'm concerned" She answers gently "And you are smaller, but to be fair there I'm a troll so that's kind of major edge there. As for 'younger' like years? You know, a turtle lives a lot longer than a cat, so a cat can be old while a turtle, even if it came into this world, is still very young.. so arguably, that cat is soon older.. and that's okay.. a bit scary I bet, but okay. Remember, we're all of us on a great big loop that travels through time. Vegard was old, but now he's back in me. Maybe in a hundred years you'll meet the next me and call me little sister? Who knows? Maybe in TWO Hundred years we'll both be born at the same time and have the same real mom and dad? For now, I have you, I call you might little brother, if that bothers you, you let me know and I'll call you something else, but I'll never not love you"
