When the Envy Bug Bites Raven is envious of Eagle's cool new landing lights, and wants a new array for himself. Headmaster Crane warns him about the dangers of envy, urging him to be content with what he has. But Raven wants what he wants, so when Vulture lures him to his Starflight Emporium & Trading Post, the cadet trades away his old tow-line plus some work IOUs for a brand new lighting array. Still envious of other friends' possessions, he continues to trade in again and again for newer, bigger and better gizmos and gadgets... getting deeper and deeper into IOU work debt to Vulture... finally ending up with his old tow-line again. But when Starling gets into trouble on the moon and needs Raven's help, he discovers that the tow-line turns out to be more valuable than any new gadgets he'd coveted.
