Emma thinks she’s like the tides, and Lily is the moon. The tides move ups and down as the moon waxes and wanes.

Emma thinks Lily always is the one that leads, drives, runs, etc. Lily, the synonym of dominance. However, this time, she’s the one that decides to leave first.

The tides and be free. The tides can move where they want to move to. But without the moon, the tides can no longer reach the sky.
