Erza wasn't sure about this idea Cana had but the doctor had managed to convince Gray to go along with it and he seemed to hope that it would work so she decided that there was no harm in doing this. She only hoped that Gray wouldn't be too disappointed if it turned he couldn't be cured. Cana began doing treatments which involved giving Gray injections of a serum made from her own blood and the chemical she had created. The first time she tried it on him it was on a night when he felt an incredibly strong hunger for blood.

The reason for this was because Cana had told him that if he kept feeding on blood it would most likely set back the curing process. So for the past few days he had been doing everything he could to resist going out for blood shed. Tonight it had become too much for him. Natsu had to chain him to a chair.

"Just a little while longer Gray." Cana said. "The serum is almost finished."

Poor Gray was sweating and panting, like a dehydrated man trapped in a desert and completely  desperate for water except in this case water wouldn't do any good. His eyes flashed red and he bared his fangs.

"Hurry doc! He's really starting to lose it." Natsu said.

"It's done." Cana hurried over to them with a syringe. "Now if this works Gray you should lose all blood lust but I must warn you the serum could be toxic."

"I don't care! Just give it to me!" He hissed in a voice that almost made Cana drop the syringe. But she kept her cool and quickly made the injection. 

"Okay now just give it a minute."

He did and by the glory of God it did eliminate his blood lust but only temporarily. According to Dr. Alberona he would need daily injections to keep his blood lust under control. An hour after giving him an injection she had him give her a sample of his own blood so she could study it and see if there was any change. There was no change but she expected that. 

"It's going to take time." She had told Gray. "Just let me keep giving you these injections, refrain from drinking blood, and I'm positive we will get results."

It was hard but Gray managed to resist drinking blood and the serum did make it easier for him. Every day of next month Gray continued to let Cana give him injections of the serum and then later he allowed her to study a sample of his blood. Now of course Cana didn't always use her own blood in the serum if she did would have become anemic but Erza and Natsu gladly volunteered to give a little of their own for the serum. By month's end Cana finally saw a change in Gray's blood. It would seem that it had now become resilient to sunlight.

"You mean I can actually go out in the sun now?" Gray asked when she told him.

"Yes but only for a limited amount of time." She said. "Your body can only withstand it for so long. I recommend that you only go outside during the day for one hour."

"One hour huh? Better than nothing."

"Let's test it first. Natsu get the curtains."

"Okay."

Gray stood in front of the window of the house that had been covered by curtains. He held his breath as Natsu slowly drew back the curtains and at long last he saw it. The sun. The warm, golden sun that he had not seen in so many centuries. He never thought for one minute he would ever be able to experience it's glorious light again. He had never really appreciated just how wonderful it was to feel the sun's warmth until now.

"Alright Natsu now close the curtains." Cana said.

"Does he have to now?" Gray asked her.

"I believe it's for the best but I assure by tomorrow should be able to withstand it for an hour."

Gray was impatient and not ready to give up seeing the sun for the day but he heeded the doctor's words. However come the next morning he was determined to enjoy the sun for at least an hour. He made plans to take a walk up a certain trail, the same trail that he used to  walk with Wendy and Juliette. Walking that trail just wasn't the same at night or alone so he asked Juvia if she would accompany him and she happily agreed.

It was a sunny but cool Autumn day and the wind was blowing right much but the two of them found it to be very enjoyable. 

"Thank you for inviting me to go along with you on this." She said. 

"Thank you for accepting." He said.

"But I'm a little confused."

"About what?"

"I thought you couldn't go out in the sun. I thought you had an extremely sensitive skin condition that kept you from doing so."

"I do but Dr. Alberona has been giving me injections so that my skin can withstand the sun for awhile. I can't stay out here too long but I plan to enjoy it while I can."

"I know. It is beautiful out here today. I can't remember the last time I walked around on a day this windy." Juvia said moving her blown hair out of her face. 

"If it's bothering you then we can always go back." Gray told her.

"Oh no. It's so exciting. I feel so free as if I could fly." She said with a smiling.

"Do you take walks often?"

"Not really but I wish I did. It feels so wonderful. On a day like this I don't feel like walking. I feel like running."

And she did run. She ran about like a playful little girl who had been cooped up in the school house all day only to finally be allowed to leave and go home. Gray couldn't help but marvel at how the sunlight danced all around her making her look more and more angelic. She really was a special woman. 

But all too soon his feelings of peace turned to ones of fear when he saw Juvia running toward a familiar spot.

"No. No! Juvia! Don't go there!" He called but she couldn't hear him over the wind.

He chased after her and suddenly her appearance changed. Her clothing became torn by low branches, her feet had become bruised by stones, and her cheerful face became one of horror that was crying hysterically. He then realized that he wasn't seeing Juvia anymore he was seeing Juliette and she was running to widow's hill again.

"Stop!" He shouted to her figure. "No!"

"No! Gray! No!" She had screamed in his memory.

"No don't! Please! Juliette! Don't be afraid of me! Stop!" He called out desperately.

But despite his pleas she hurled herself off the cliff. Her scream echoing as she plunged downward to the rocks and tides below. She was gone again. 

"Gray what's wrong?" 

At the sound of her voice he was brought back from his flashback and relieved to see that she was still alive. That she had not thrown herself to her death. Without warning he threw his arms around her and held her close, terrified that if he let her go she would disappear from this world. 

"Gray what is it?" Juvia asked feeling confused by embrace. 

He pulled back and seeing her confused expression he realized that she didn't have the slightest idea to what had just happened in his mind.

"I'm sorry." He said releasing her. "When you ran I lost track of you and I...I thought that you had gone over the cliff."

"Gray I'm fine. I'm alright. Nothing's happened." She took note of his trembling hands. "You're shaking. Were you really that scared that I had fallen?"

He nodded.

"I'm sorry. I didn't mean to upset you. Is there anything I can do?"

"Could you promise me something?"

"That depends what is it?"

"Promise me that you'll stay away from this cliff. It's very dangerous and anyone could easily fall from here."

"Alright if it worries you that much then I promise won't go anywhere near this cliff."

"Thank you." He sighed. "I...I think we should go back inside. I'm not sure how much longer my body can stay out here."

"Gray?"

"Yes?"

"Is this where Juliette died?"

"Yes."

He held her again as they both looked down the cliff at the waves that crashed against the rocks below. Juvia found his actions at the moment odd but for reasons she couldn't explain she felt very safe and comforted in his arms so she didn't object to him holding her. However she was worried by his reaction, he looked as if he had actually watched someone fall from that cliff and die. Then again maybe he had. She was about to question him about it but decided that it would be best that if she just kept quiet and that they walk home together without saying another thing until they were inside.
