Crystal Venom

As Allura recovers, she spends her time enjoying the company of her father's artificial intelligence. With Sendak in custody, they decide to draw out his memories in order to learn information about Zarkon and the Galra empire. While waiting, the Castle begins displaying strange behavior: Hunk and Pidge are attacked by malfunctioning kitchen equipment and later stuck in zero-G, Lance is locked in a cryo chamber and later almost sucked out of an air lock while Keith is attacked by a rogue training droid. Shiro monitors Sendak and begins interrogating him, but is mentally tormented by Sendak's voice prompting him to eject Sendak into space. Coran concludes that Alfor's AI has been corrupted by the lingering effects of the Galran crystal as they try to stop Allura, convinced that Alfor is taking her back to Altea, from driving the Castle-ship into an imploding star. At the urging of the real Alfor, Allura tearfully destroys her father's memories in order to save the ship. Despite the loss, Allura stands strong and maintains that Voltron is her father's legacy.
