how's this for a storyline for a future episode?

Regina's and Robin's romance is getting serious and they start seeing more and more and while they are spending a romantic day together, Robin proposes to Regina and Regina is taken into suprise and doesn't give him an answer right away so she leaves leaving Robin feeling rejected. Regina is under a lot of stress while processing through her head about the proposal. She remembers how hard it was to lose Daniel and doesn't want to go through that again. She goes to see Robin again and apologizes for running off. She tells him about her first love, Daniel and how she lost him and didn't want to go through that again. Robin assures her she doesn't have to. Regina asks Robin if he's willing to ask again and he does and she says "YES!" However Zelena overhears everything and is determined to put it an end to the engagement. Meanwhile in the enchanted forest past, we learn how Regina and Daniel meet. I haven't figured out the storyline for that but all I know is that I desperately want to see an episode where we learn how Regina and Daniel met. Would love to see Noah Bean come back as Daniel! :)
