Juvia has never seen Gray-sama cry. The first and only time was when a spear went through her heart.
His face went from shocked,to pissed,to terrified in a sad way. She saw the tears well in his eyes.
She smiles at him feeling the tears roll down her cheeks."Please...Don't cry... Gray-sama... "She says before coughing up blood.
But he couldn't hold back. He started crying causing her heart to break in a different way. The spear left her body and she lay down lifeless.
Gray ran/crawled towards her and rested her head on his legs." Juvia!"He called a few tears staining her cheeks.
Even though he knew she was gone he called her name over and over again.
"Juvia feels sad. Gray-sama is crying for her..."
Gray tried living on without her but he couldn't. His note read:
Ill be with Juvia. I can't see her cry again..
