When Regina first meets Robin, after Tink's pixie dust, she believes that she is in love. But only to find out that he's married. She doesn't believe that she can handle another heartbreak, so her solution is to go to Rumple, and ask for a forgetting potion. After the curse is cast, a strange man enters Storybrooke with a young boy. Regina believes that he looks vaguely familiar, but she has never seen him before. Or so she thinks.
