It had been a month since it happened. Since that demon took you from the four people who loved you more than anyone else in the world. Each one of them loved you. Four hearts broke that day. Dean would sit and drink. Hoping the alcohol would chase the memories away. He saw you as a little sister and always made sure you were safe. He chuckled as he remembered all the times you would argue about going on hunts when he didn't want you too. You always won. His eyes watered as he realized he would never hear you tell him no or that you were going like it not ever again. As he watched your body burn he broke down.
Sam also counted you as a little sister. He couldn't even bring himself to go into the library anymore. You would sit with him for hours and research or read up on creatures you needed or wanted to learn about. Unlike Dean, you would never complain. He smiled softly as he remembered one time having a race to see who could read the most lore books in one day. Of course, you won. When they burned your body Sam threw in your favorite lore book. You never went anywhere without it.
Castiel was an angel who was no stranger to the feeling of loss and mourning. Losing you hurt the angel worse than any loss he has felt on earth. You were always so sweet and would always console him when someone was being harsh with him. All the times Castiel would feel like he wasn't good enough or worth anything you would tell him all the reasons why that wasn't true. You would often tell your other two brothers Cas was your favorite. It always made the angel smile. As he watched you burn he whispered, "you were my favorite too Y/N,".
Then there was Jack. Jack was more than a brother to you, Jack was your true love and he felt the same way about you. You two were pretty much inseparable. You two had so many firsts together. First kiss, first date, first time you both said I love you. Jack tried so hard to save you. To heal you. When he couldn't the poor nephilim broke down. He felt helpless and useless watching the body of the girl he loved burn. What was he supposed to do without you? "I'm sorry," was all he could manage to whisper as the fire consumed your body.
