"Once Upon A Time" Season 4, Episode 6, titled "Family Business," airs Sunday, Nov. 2, on ABC. Belle (Emilie de Ravin) and Rumplestiltskin (Robert Carlyle) get the spotlight in this week's new episode. Queen Elsa (Georgina Haig) and Anna (Elizabeth Lail) are also expected to have more scenes together as the series dives deeper into the mysterious history of the Snow Queen (Elizabeth Mitchell).

Spoiler alert: This feature contains Once Upon A Time Season 4 spoilers. Read at your own risk if you have not seen the previous episodes.

"Belle tries to use Gold's dagger to force him to locate the Snow Queen, so that the townspeople can find out her plans and learn why she wiped Emma's memories," reads the OUAT 4x6 spoilers on TV.com.

Rumple/Gold acts disappointed, as seen in the promo clip for this week's new episode. "I trusted you," he tells Belle, as she uses the Dark One's dagger. It remains to be seen how Gold is going to fake obedience, since Belle does not have the real dagger.

"In the past, Belle convinces Anna to take her to Grand Pabbie so that she can recover her memories of her mother Colette," the synopsis continues, hinting of a deeper back story in Once Upon A Time Season 4, Episode 6.

In the same promo clip, Ana is seen falling off a cliff. Does someone save the Arendelle princess, or does she wind up manifesting her own magic?

"Truth will be revealed," says the OUAT 4x6 promo clip voice over. Cut to the Snow Queen looking on as a pick up wreck is pulled up from the ground in Storybrooke's forest edge. And Emma (Jennifer Morrison) and Hook (Colin O'Donoghue) find an old scroll, which "isn't from our world."

It will be recalled that Elsa's and Anna's parents wrote a scroll which contained their farewell message to their daughters. Emma and Hook may have found this scroll, or something else.

"Some secrets are better left buried," the Snow Queen tells someone who appears to be in a prison cell. Who could she be speaking to? OUAT viewers hope to find a lot of answers in Episode 6.

Once Upon A Time Season 4 airs Sundays on ABC.
