Stephen McCranie's Space Boy #4

Cassie and Dave are suspicious of Oliver, but Amy visits Oliver's house, and meets his guardian Dr. Kim. Amy and Oliver enjoy being together, but Commander Saito warns Oliver that if Amy learns the (yet unspecified) truth about Oliver's existence, she will be killed as a threat to national security. Oliver breaks off the relationship. Amy speaks with Jemmah, and spends time with her ag club friends, but still determines to talk more, and more deeply, with Oliver.
