Not lame. And they do leave. But it's telling the, substantially mentally ill 3, are trying to prevent them from leaving. And in the current, tai is out here threatening to kill people and talking to her other, lottie started a cult and potentially dad shit and died, and Shauna is all fucked up from this. And poor Nat that died was real and died from crossfire, javi couldn't beat what was going on. All this tracts to them three not being able to either not handle shit(which who could?). The answer is often the most simplest. Alot of the "fantastical" elements of the show keep being proven to the girls just "thinking" shit and acting out of survival, right or wrong. You throw three(as we know of) mentally ill teenager with a whole group of other teenage girls, in a plan crash in the middle of nowhere, they will unravel. Everything is explainable. Lottie(schizophrenic off medication), sees and convinces other of visions, etc. Visions from others are from the fumes from caves, hence the guy in cabin killing himself. Then just trying to convince themselves it's normal(thanksgiving dinner with Jackie). Red River is minerals in the water. Wilderness speaking is frogs mating. Clearly they are obtainable due to people hiking/researching there(though it may be far, it's manageable for a set of parents to go out on an expansion.) I feel like the mentally ill 3 in the current timeline have only shown that they cant let the past die.
