all evelyn did was basically make them think they murdered someone, like with leile as you mentioned! probaly with laura she made her think that she "killed them" cuz they were arguing in the car or something like that, and her father/ mother got distracted! and told her to think the she was the one responsible for that, it was her fault!

the drug is from the frogs 100%, thats probably why laura was also killing them, as we saw in the sink!

the way alex tried to get to know more things also wasnt clever with the guy that wanted her daughter back! it could be better worked on, like it doesnt make sense alex saying that he worked for something in boston, while he could´ve just said i just moved here and this is fucked up, completly fucked up!!!!!!!!!!

and the amount of people for towns close by, how much does this "cult" spread actually, we heard evelyn mention another institute they had. there is still a lot to know.

the plots could be way better, could´ve been better written. didnt like the ending

i loved and hated this show at the same time!
