Alice had been seeing you in her vision for about 25 years and was waiting for you because you were her missing part!
You were Bella's brother, you were very attached to Bella, so like Bella, you decided to move in to your father, and Charlie accepted it, after all, you were his only son!
It wasn't a simple life in Florida, but it was nice, you were like a party monster, but it wouldn't happen without Bella, it was unhappy. And you went to Forks, settled in, and the next day you went to school with your sister, and Bella immediately took you to the skull to introduce you to her boyfriend, Edward Cullen.
When you entered the cafeteria, Bella immediately took you to Edward and his family, Edward Cullen, Jasper Cullen, Rosalie Cullen, Emmet Cullen and Alice Cullen at the table! Everyone at the table knew that Alice had been waiting for you for 25 years (Of course you didn't know that) Because Alice was talking about you for hours and it could be annoying for them sometimes.
