Star and Marco prepare for the Midnight Warrior Blowout Sale at Quest Buy. During the event, they meet fellow shoppers who will stop at nothing to get the best knight gear. After meeting female squire Higgs, she ridicules Marco by telling him that in spite of being named squire, it was handed to him under the impression that he's Star's boyfriend, which he denies. With all their efforts, Star reassures him that she only named him squire so they can go on adventures again like they used to. They finish the blowout sale by buying random, fun things instead of suitable knight gear much to the praise of the knights and Higgs' chagrin.
