Exactly right.
I keep seeing people on other forums say Erin is stupid and that concerns me because if people think of her through that lense, it’s much easier to think that she couldn’t possibly premeditate such a thing.
I have no doubt if Erin was hypothetically planning what she is accused of, that she would know every single thing about the topic. The thing she is not good at is people and predicting how they will behave, which is her undoing here, IMO.
If it wasn’t for Simon taking the inlaws to hospital and the hospital quickly cottoning on that this was Death Cap poisoning, it’s possible we would not be here.
I’m sure she didn’t think her friends would betray her (in her mind) and share private photos she shared. Or disclosing to the police that she hid powdered mushrooms in the kids food.
I’m sure she didn’t think police would be looking at her bank statements days after the lunch and seeing her dispose of the dehydrator, etc. I doubt they would have even started looking at her so soon if it wasn’t for her refusing to answer the questions initially. IMO
