Convinced that Tess (Emilie de Ravin) is the fourth alien, the kids agree to stick together and get to the bottom of the situation. Confusion strikes again, however, when Tess vows that she is not Nasedo (Jim Ortlieb); rather, she claims to be an alien who was left behind when Max (Jason Behr), Isabel (Katherine Heigl), and Michael (Brendan Fehr) emerged from their pods. Max is unsure of what to do when Tess explains that she can show him the pod chamber where they were born. Meanwhile, Isabel and Michael try to come to grips with the romantic dreams they've been having about one another despite the fact that they are both involved in serious relationships.
