Unchain My Heart, Part 3.After an argument about whose problem Vam-Mi is, Venus leaves the Turtles to study a pile of ancient Shinobi scrolls by herself, in an attempt to learn a Shinobi magic spell to destroy vampires. Vam-Mi tracks her down and attacks her, however Leonardo appears and saves the day. Bonesteel, who is also currently chasing Venus, obtains Vam-Mi's heart during her confrontation with Vam-Mi. After returning to the Turtles' lair and admitting that she had lost the heart during the fray, Leonardo convinces the Turtles that if they find Bonesteel, they'll find the heart. Both the Turtles and Vam-Mi end up tracking down Bonesteel at the same time, and after a fight between the three parties, Bonesteel captures Vam-Mi & Co. in a cage, while the Turtles end up with the heart back in their possession. They lock the heart in a safe, unsure about what to do with it now that they have it back.
