Mary Margaret using Regina's teardrop in "Second Star to the Right" is a hint to their relationship getting to an even higher level. With Zelena's curse altering reality, the only way for Regina to be safe (since the Wicked Witch's curse would make her have never been born) would be merging with her former archenemy.
