It is from Steven UniverseLapis was trapped in a mirror, Steven released her. She wanted to get home but her gem was broken so she couldnt use her power. Again, Steven helped her and she finally got to go home. When her home-world learned of Steven and the Crystal Gems they went for them, taking Lapis as prisoner with them for reasons. After a great epic episode, Lapis captures a badguy using water and pulls them both to the bottom of the ocean where they both are still (at this point in the show).My picture is, perhaps the weight of the ocean on top of her isn't so bad.
