Once Upon a Time in Wonderland is heating up, and based on this promo Season 1, Episode 5: "Heart of Stone" could be very interesting.

It looks like the Red Queen, for reasons that remain a mystery right now, wants to team up with Alice next week. But will Alice be willing to join forces with her enemy? In this promo, it looks like she entertains the idea, but by the end of the video she seems to have turned on the woman formerly known as Anastasia.

Want to know more? Here's the official synopsis of the episode:

In a flashback, Will Scarlet and Anastasia jump through the looking glass to enter Wonderland against her mother’s wishes, since she disapproves of Will. They both soon realize that life in Wonderland isn’t exactly what they had both imagined. After being humiliated while attending a ball at the palace, Ana convinces Will to steal the crown jewels in order to get them out of poverty, but in an instant, Ana is caught red handed by the King who makes her a proposition she can’t refuse – to marry him and be his Queen to avoid prosecution. Meanwhile, in current Wonderland, the Red Queen convinces Alice to help her acquire magic dust in exchange for information about Cyrus, who in turn has managed to skillfully escape Jafar’s castle leaving the White Rabbit in a compromising situation.

Once Upon a Time in Wonderland airs Thursdays at 8 p.m. ET on ABC.
