I definitely think the romance would be welcomed. I noticed in this weeks episode that Geno said to betty something about there has "only always been one man for her/or man in her life." I think he was referring to Daniel and that it was a glimpse for us to speculate the new romance. Betty deserves happiness; so does Daniel. Time they found "love" when they least expected it. That's always been the best kind of love.
Yes!! since the show is coming to a conclusion i would love to see the romance between Betty and Daniel start that would be like the perfect ending to the show!!!
