Jeremiah and Kurdy are sent to contact an elusive group led by a mysterious "Steve" but get captured. One of his captors is Michelle, a woman he met (in flashback) back at his empty home five years ago after his brother died. They were intimately involved back then, and we find out she's the one who gave Jeremiah the idea for writing notes to his dead father. In the present it turns out "Steve" is Michelle. Her operation is working heavily to get knowledge out, and she also has a 5-year old son. One guy accuses Michelle of skimming and the guys follow her and find out she's collecting art, and agrees to work with Thunder Mountain. Then Michelle comes back to lay down the law on the guy who accused her of skimming and the guys head out with as Jeremiah and Michelle think about getting together in the future.
