Darcy knew that Diana left the island and that Ella gave birth to Phil's daughter. Part of her wanted to reach out to him and see how he was doing with everything, but she was still conflicted about him deciding to father a child with another woman without even asking her if she was interested. She'd finally acknowledged, at least to herself, that she was developing feelings for Phil and she wasn't sure how to deal with that.
When she heard that he hadn't given the baby to Arva yet, she decided to go and meet her. She couldn't avoid him, nor did she want to, and she imagined that it might be difficult to decide to give her child over to the goddess.
Ella told her that Phil had taken the baby for a walk and she was looking for him when she heard him talking to his daughter. Her breath caught when he said that she was special. Was it possible he was developing feelings too? If so, how would that even work here?
Forcing herself to remain calm, she plastered on a smile and walked around the corner into sight, pretending she hadn't overheard him. "Hey, you," she said. "I was hoping to meet the little one before you hand her over."
