Yes, he does, and she is correct.

"...okay fine," Natsu shrugged. "Guess it's harmless enough as long as it's worded right... Let's see..."

Juvia waited in anticipation as Natsu considered how to word the wish. "Don't worry about being too precise, Master, I won't screw anything up deliberately," Lucy told Natsu.

"Alright, alright," he nodded. He then decided to go with the obvious wording. "I wish that Gray would act on any potential romantic feelings he has for Juvia without worrying about the petty stuff like personal bullshit."

"Good wish, Master~!" Lucy nodded, grinning as she snapped her fingers, casting her spell on Gray.

Gray was in the process of putting his clothes back on, grumbling as he was mocked yet again for his careless habits, when he paused, Lucy's spell taking hold. He suddenly couldn't stop thinking about his feelings for Juvia... And why he had never acted on them. Primarily his desire to prove to himself that he was worthy of her love.

As his perspective expanded, he began to realize how silly those reasons were. He was already worthy, at least in Juvia's eyes. So long as he cared about her back, and intended to be a loving partner to her, then that was what counted. He gathered his nerve, and slowly turned to walk towards Natsu, Lucy and Juvia. "...did you guys do something?" he asked them.

"Nothing much, just gave you a fresh perspective," Lucy grinned, mischief all over her face, but she was very happy to be of help to Gray and Juvia.

"Don't thank me, Ice For Brains, I did it because Juvia asked me to," Natsu grunted, crossing his arms.

"I wasn't going to thank you anyway, you pyromaniac," Gray snorted, but couldn't hide the appreciative smile. "Juvia, mind if we go somewhere private to... talk?" he asked her with a blush.

"YES! A million times, yes, Gray-sama!" Juvia squeed, hugging him, and looked towards Natsu. "Thank you!" she gushed as they headed off.

"Heh, see, we can improve the sex lives of others with my powers too..." Lucy grinned, excited for what was to come.

"Indeed..." Natsu smirked. "...though Juvia could do so much better, in my opinion." Lucy only giggled at that.
