Robin loses Regina's heart after Rumplestiltskin takes it. Regina's response both shocks and stuns Robin.

Robin was falling for Regina. There was no denying it at this point. She was sneaky, and ruthless, she didn't let anyone get in her way, not even him. There was also the fact that she was downright beautiful, but her intriguing personality made everything shine even more.

When he had found her in the woods, he had seen a different side of her. She was upset, sad, broken. The Evil Queen was the last person he had expected to see in this state of mind, but there she was. And then she had given him her heart to protect, and he had felt a stronger connection to her in that moment than he had ever felt before. But, of course, the Dark One had to ruin it, and now his precious Regina's heart was gone. He didn't know how to tell her, but he knew he had to, so he knocked on her door. She opened it almost right away.

"Robin, I…" she said, "I didn't expect to see you here. Is everything okay?"

"Regina," he replied, kind of distraught, "I'm so sorry."

"What? What's wrong?"

"Rumplestiltskin. He- he took your heart. I'm sorry. He was threatening Roland. I couldn't watch my son die." Tears were running down Robin's face now, and Regina had reached up and began wiping them away with her thumb.

"It's okay," she whispered, her own voice cracking, "I know you tried your hardest. You had to protect your son. And if this is going to be the possible last time we see each other, because, let's face it, who knows what the witch is going to do now with all these ingredients, I just want you to know…"

And her lips were on his, passionately kissing him. The first and last time. It was Regina who broke the kiss first.

"Do you think… Do you think you could come in?" she asked, tears rolling down her face now, makeup staining her cheeks, "I don't want to be alone when the witch casts her spell."

"Of course," he replied, "But do you think we could go get Roland first? He's just at the diner."

Regina nodded and smiled, as he took her arm and they walked to pick up his son.
