If Emma hadn’t saved Marian, and Robin found out Regina had her beheaded that wouldn ‘t have been good news either. I think somehow, Regina and Robin will end up together, but there will be lots of obstacles just like the other relationships on the show. They are soul mates, but the timing isn ‘t right yet. When Tinkerbell led Regina to Robin the first time, he probably hadn’t met Marian yet. Tink was right about one thing: Regina was ruining her own life by choosing to give into her vengeance .
