Ryan and Jarrah have been kicked out of the camp without the antidote but Saskia steals it, gives it to Josh and he gives it to Ryan. When Ryan got the antidote, they start their trip to find Dr. Hamilton but they notice that they are followed but Ryan finds out that it's Gabe. Gabe is there because he wants the antidote and after some discussion, Ryan gives it to him. Meanwhile, Jarrah is out looking for water but instead she finds Natasha and the Mystery Girl who's called Hope (Luisa Mitchell). Natasha has injured her ankle so Jarrah says she will go and get Ryan but is she really going to tell Ryan.
