As Serenity's eyes opened, she was back at the Heartfilia manor (I'm just going to say Lucy eventually bought back the manision). She was seated at the dinning table, a delicious meal sat in front of her. After taking a big bite of spaghetti, she notice she wasn't alone. Her mother and grandmother sat to the right of her, while the rest of the dinning seats were filled with her spirits. 

"Everyone!" She said, not even noticing that this should be impossible. Also sitting with them was two new spirits, the last of the golden keys, Libra and Pisces. She had all of the 12 zodiac keys! The smile never left her face
