Emma and Regina's growing feud seemed ready to explode when suddenly they found themselves working together. A mine on the outskirts of town had begun to collapse and Henry had run in there looking for proof of the Curse. For the first time, we and Emma saw the Mayor genuinely seem concerned about Henry and both women put aside their anger toward each other to save him. But as soon as he was safe, Regina made it clear that nothing had changed, and while she had to accept that Emma was staying in Storybrooke—and working for her as a Sheriff's Deputy to boot—she didn't have to like it.
