This takes place right after Belle and Ariel had taken Pandora's box from Wendy's brother. Ariel is about the take the box back to Neverland and give it to Rumplestiltskin.
Belle looks at Ariel as she begins to swim towards Neverland and Rumple. Belle watches as the only link she has to the man she loves swims away, with her the last remaining chance that she might be able to see him.
"WAIT!" Belle screams out before she can even comprehend what she had just said. Ariel turns around and looks at Belle in a quizzical manor. "I want to go with you." Ariel just stares at this small woman. "I want to go to Neverland."
Ariel shakes her head. "It is not a good idea. You are much safer here, in Storybrooke."
Belle looks at the mermaid, with a face of determination and begging. "The man I love is there; wouldn't you do anything to get back to Eric?"
Ariel considers her for a while. She knows the feeling of longing for the man you love. Belle was right; she understood what it was like to need to be close to the person you love. Ariel looked at the bracelet she held in her hand. She knew that the powers were still good for about 12 more hours, and it would turn Belle into a mermaid, just as it had given her legs mere moments ago. Ariel tossed the bracelet to Belle. Belle caught the glimmering object in her hands.
"You know that the journey will be long and dangerous, but not as dangerous as Neverland is. You understand that by coming with me, you run the risk of never returning?"
"Yes, but it is worth it to see Rumple one last time." With that Belle slipped the bracelet on and immediately her thin legs turned into an iridescent yellow tail. Belle tested the tail a few times, it was a little difficult for her to control, but she soon got the hang of it. She swam out to Ariel.
"Ready?" Ariel said as she clutched the box. "To Neverland."
