Kind of a spin-off of Hook asking David for Emma's hand in marriage because this is the relationship that should be happening.
"Why do you keep fidgeting?" Emma asked. "You're making me nervous."
"Sorry," Regina said. "I'm just nervous."
"About what?" Emma asked. "For once, the town is actually peaceful."
"Not about the town," Regina said. "I have plans later that I'm nervous about. Your father suddenly decided that my sword skills weren't up to par."
Emma laughed. "He's going to teach you sword fighting?"
"No, I already know how to," Regina said. "He's just improving my skills."
"Why do you even need to know how to sword fight?" Emma asked. "You have magic. Magic literally beats everything."
"Until you're wearing a magic bracelet that prevents you from using magic," Regina countered. She smirked when Emma paled. She hadn't thought of that.
"Just don't get stabbed," Emma mumbled.
"Why did you even ask me to do this?" David asked. "You don't need help with sword fighting. I seem to distinctly remember you holding your own when fighting the Count."
"I didn't really come here to get a lesson in sword fighting," Regina said. "Although if you have some tips I would love them. Better safe than sorry."
David chuckled. "So then why ask me to get together with you?"
"I know that we've had rough patches in our past, but I was hoping that you could see past all of that and look more at how much I love your daughter," Regina said.
"Of course," David said. "I'm happy that you and Emma are together. You make each other very happy."
Regina smiled. "I can agree with that."
"Was that all that you needed?" David asked. "Reassurance that I was okay with your relationship with Emma?"
"No," Regina said. "I just more needed to hear that before I continued onto the next part of what I have to say."
"Okay," David said slowly. "Continue then."
Regina took a deep breath. "I was hoping to get your blessing to ask Emma to marry me."
David's eyes widened before his face broke out into a huge smile. He walked forward and gave Regina a huge hug. "Of course you have my blessing."
Regina sighed in relief. "Thank you."
David pulled away from Regina, surprise on his face. "Did you think that I would say no?"
"I didn't know what you were going to say," Regina admitted. "We've had a rough past together, but Emma and I have a great future ahead. I didn't know how you felt about things."
"I am so happy for both of you," David said. "You both deserve to have your happy endings, especially in each other."
"Thank you," Regina said. "Now I just have to plan the proposal."
David and Regina: the most underappreciated friendship that could bloom.
