From Antisense Scanslations: "I don't need this ring anyway!" She thought she saw the last of the promise ring from her ex-boyfriend until a water god came out of her bathtub and gave her 3 seconds to answer his question! Because of her sadness she lied to his second question so he takes it upon himself to purify her with his water; tentacle style!
