Watermelon: Time for the world to meet Watermelon Tourmaline!
Watermelon: Diamond, you were meant to join my army! So, whaddya say?
Diamond: Yes. (Episode starts out)
Pearl: Diamond! You traitor!
Steven: How could you do this to us?
Diamond: Oh, Steven. Don't you understand the meaning of fate? This is my fate. Yours is death. (Pulls out staff)
Diamond: And it's soon.
Watermelon: But how shall we speed this up?
Diamond: Shall you fuse with Sapphire?
Sapphire: Oh yes. Bloodstone ought to take care of them.
Garnet: Get them!
Diamond: Let me hold them off. (Turns Crystalline. Shoots mini Crystal seeds, and it makes a wall of Crystal. Waternelon and Sapphire begin to dance, and they become Bloodstone)
Bloodstone: Let's do this. (Summons a bag of spiked mortars. They throw them, and they blow up. Pearl's gem cracks)
Garnet: Pearl! (Charges at Bloodstone, but hits her away. Her gems crack)
Amethyst: Garnet! (Whips Bloodstone, but Bloodstone pulls in Amethyst, and cracks her gem. They head toward Steven)
Diamond: Leave him. I'll finish him off. (They defuse)
Watermelon: You may have the honors of defeating them, once and for all. (Diamond walks up to them)
Diamond: There is something I have to do first.
Watermelon: Well, spit it out!
Diamond: This. (Shoots a blast at Sapphire which paralyzes her. He hits her gem, and it shatters. He steps on the remains)
Watermelon: Traitor! (Diamond shoots crystals at the gems, which heals their cracks)
Diamond: It's just you and me now. (Pulls out knife. They clash in an epic showdown)
Steven: I knew you would never betray us!
Amethyst: Why didn't you just fuse with them and make it quicker?
Diamond: Well, his influence may have gotten to me.
Watermelon: Oh, really? (Uses psychic, and forces him to dance. They become a gem mass)
Diamond(voice): I won't let you hurt the gems! (The gem mass defuses. Diamond then gets cut on the cheek by a knife. Diamond hits Watermelon, and ascends to the sky. He then charges down, and hits Watermelon. His gem disintegrates)
Diamond: And the finishing touch. (Puts his staff on the ground, and it emits a healing pulse. The world returns to normal)
Diamond: And everything ends well. (A star appears in the Sky. The iris closes in on it. Episode ends)
