The romance of Paige and Walter (Katharine McPhee, Elyes Gabel) was just getting started when this show’s previous year ended — and now, it takes what’s termed "a shocking turn" in the Season 4 finale, "A Life in the Sand." The story is set in Northeast Africa, where the team faces a literal minefield to try to save the locals. Toby and Happy (Eddie Kaye Thomas, Jadyn Wong) reach a decision about something major. Robert Patrick and Ari Stidham also star.
