Lori, still trying to get over being attacked, insists everyone go on an outing. Declan and Kyle realize her picnic spot is right next to Zzyxx and try to dissuade her, but Lori is having none of it. Then,at the last moment,the reprogrammed Jessi invites herself along. When Lori taunts everyone into following her into some tunnels that run under Zzyx, all hell breaks loose.
Jessi and Kyle are overcome by flashbacks. For Kyle, what he learns supplies important information he can trust Foss but not Taylor. For Jessi, things don't turn out quite so well.
Freaked out by seeing herself suspended in the pod, she unleashes a burst of energy that makes a vent burst, the air fill with gas and puts the whole place in lockdown .
