PRODIGAL SON THEORY!! SPOILERS NEXT PARAGRAPH!!
Skipping the explanation: Watkins is the reason why Ainsley is a killer.
John Watkins was Ainsley's "imaginary friend" when she was little. We know Watkins was a killer at that point in his life.
The season 2 teaser also has (I'm assuming) Ainsley as a little girl. She appears to be having a tea party with stuffed animals. There's an empty seat, possibly for an imaginary friend. I think the empty seat is for John Watkins. Reminding us that he visited Ainsley when she was little.
My theory is that Watkins was trying to teach Ainsley about killing. He knew that Martin intended to kill Malcolm, and we know (when Malcolm's an adult) that Watkins wants to make Malcolm a killer.
What if he wanted to make Ainsley a killer because he knew that there wouldn't be a chance to make Malcolm one? Maybe he even brought her animals to practice on.
Since Ainsley was so young when Martin was arrested, (and the tunnel was closed, ending the visits) she wouldn't necessarily remember everything she was taught. But if Watkins did bring her animals to practice on, and if she liked it, some part of Ainsley's subconscious might have remembered what that felt like.
When she slit Endicott's throat, her face is calm. Then there was some time before she stabs him multiple times. When Endicott falls, dead, and she's just standing there, Ainsley isn't ashamed or shocked by what's she's done. She's just calm and is curious why that just happened.
That's not a normal reaction. While her technique doesn't seem professional, her reaction seems like it's not her first time killing.
I think that's because of John Watkins and not because she's Martin Whitley's daughter. Thanks for sitting through that!
