Natsu is shocked at the point when he sees his long lost friend Lisanna, in fact everyone was, except for Lucy. Lucy didnt know Lisanna since she joined about 2 years ago. The guild threw a party for Lisannas return which left Lucy out. She felt so left out that she wasnt noticed. She decides to leave Fairytail on her own. On her way she comes across the Water Dragon Elizabeth. Lucy asks to make her to make her a water dragon slayer and Elizabeth accpets. They spend 3 years together. After these memorable years, Elizabeth leaves to where all the other dragons left to. Before she leaves Elizabeth leaves her a very powerful spell, the water droplet of life which resurects someone they will lose in the future. She comes back to Fairytail . Everyone questioned her and that sort of made Lucy more there. The person that was most happy was their Fire Dtagon Slayer Natsu. From that point foward Natsu payed more attention to her. However the powerful spell that Elizabeth gave lucy might change what might've been a happy ending.
