After Jeremiah discovers that a page is missing from Simon's journal, him and Kurdy try to find where this missing page might be. The trail leads to Lee Chen and Jeremiah and Kurdy find damning evidence that Lee has been in secret contact with someone outside of Thunder Mountain. With the missing page in hand, Jeremiah drives out of Thunder Mountain, defying Markus and angering Kurdy. Jeremiah and Kurdy head for Clarefield to find out just who Simon was dealing with before he died. Reluctantly, Kurdy agrees to go along but warns this will be his last mission with Jeremiah. Kurdy wants to go back to Thunder Mountain and build a life with Elizabeth.

As Markus and Erin continue toward St. Louis where a meeting is being held to form an Alliance of towns, Elizabeth picks up Theo and learns that Jeremiah and Kurdy have been asking about a sect called the Brothers of the Apocalypse. While she and Theo detour to check on them, traitorous Lee Chen is picked up by a well-equipped military force. As Jeremiah and Kurdy learn what the sect's leader knows about the Big Death, Elizabeth arrives only to be intercepted by Ezekiel who warns that she has been followed. As Ezekiel tries to get the group away to safety, gunfire erupts. Elizabeth is mortally wounded and for Kurdy, it's the final straw. Kurdy takes the Rover and drives away with her, leaving Jeremiah behind.
