WARNING: The following contains spoilers for Jurassic World: Camp Cretaceous Season 4, now streaming on Netflix.
In Jurassic World: Camp Cretaceous, it's safe to say the series' bravest character has been the diminutive, dogged Yaz. She's been a badass throughout, cutting a tomboy figure as she helps Darius lead the teens to safety time and time again. Darius might be the brain, and while Yaz contributes to strategy too, she's the brawn of it all, guiding them physically as she's athletic. However, come Season 4, it's revealed all the dangers they've faced has left Yaz totally broken and suffering intensely from her trauma.
Yaz is the most gifted of the bunch, outrunning raptors, the Scorpios Rex and a bevy of other dinosaurs over the seasons. She's nimble, agile and fearless, which is why she runs point on such deadly missions, whether it be stealing intel from Dr. Wu's folks, or distracting creatures to aid her friends' escapes.
Things change drastically this season, however, as Yaz is experiencing shock in the field. There are a couple times on this mysterious new island when she's frozen stiff and has to be jolted by Kenji and Co. She's petrified of the action, which comes to a head when she keeps having nightmares of all the dinosaurs attacking her and her crew.
Yaz wakes up screaming and such, with grief and paranoia setting in, to the point that her teammates and even the scientist, Mae, can tell something's wrong. She eventually admits to her clique that she's scared and thinks they may die as they try to get home -- which are fears the others do have as well. A lot of it has to do with all the attacks they've endured in the show, with mercenaries also haunting them as they sought a path to their respective families last season, but in Yaz's case, it's quite extreme.
She can't get over how they almost lost Brooklynn to Wu's goons and how Sammy got poisoned by the Scorpios, almost dying in Yaz's hands. Yaz was the one who actually raced to get the antidote, and seeing as Sammy is like a sister to her, it's weighed heavily on Yaz since, especially as she usually doesn't get attached to people.
Now that Yaz finally has an idea of family, she can't help but think they'll all die soon, which is a very dark story in a show that's relatively light. Still, it's most welcomed to teach teenage viewers the effects of these wars of attritions, with a dejected Yaz clueless over what solution there is for her flailing mental health.
Luckily, her friends are there to support her, confirming she's more human than we thought, although this will get tested in Season 5. With Kash mind-controlling dinosaurs and Kenji's dad, Dan, present with robot-dogs as well, the mission will only get more treacherous, which may damage Yaz's psyche even more.
See how Yaz is mentally damaged in Jurassic World: Camp Cretaceous Season 4, now streaming on Netflix.
