I agree that this Blind Item just screams Once Upon a Time, and think things definitely aren’t looking good for Robin. Now I think if this does cause Regina to backslide, it won’t be the Charmings she goes after, but Zelena. Zelena may play a role in Robin’s death, and that would be enough of a reason for Regina to target her sister. Maybe that’s the real reason for having Zelena around, so that they can have an excuse for Regina to revert back to her old habits. Regina’s come to far to turn on the Charmings yet again, but her feud with Zelena remains unresolved.
