Viewers learned the connection between Belle and Anna on Once Upon a Time Season 4 Episode 6, as Rumple's main squeeze revealed how she was responsible for Elsa's sister disappearing.
Looking ahead to Once Upon a Time Season 4 Episode 7, meanwhile, the connection between The Snow Queen and Emma will be further explored.
Much to the frightened chagrin of a certain Storybrooke heroine? Very much so, according to the official ABC teaser:
As you can see above, Emma will grow scared of her escalating powers, isolating herself from loved ones to protect them and she seeking help from Mr. Gold for the potentially fatal problem.
Elsewhere, in the Arendelle of the past, The Snow Queen will do all she can to ignite a rivalry between Anna and Elsa.
