Regardless if Dustin heard it or not, we are to understand from JL there was this hearsay story (whatever it entails) that was being shared among the team?!
JL called it a twisted betrayal and stuff of parent’s nightmares and wanted to protect her son. I say that conveying that it held a lot of gravity to her and I do believe she took it seriously.
If JL heard it, clearly it was passed down to her years later. So others on the team also have heard the story!? Wait, so did they know as it was originally transpiring, shortly after or years later? How did the story even first become known to the team to even be passed down to JL?
So that means one of 4 things
1. They have never heard the hearsay story and have zero idea what JL is referring to.
2. They have heard the hearsay story, didn’t believe it was plausible and didn’t investigate it.
3. They heard it, look into it and determined it was false.
4. They have heard it, think it is plausible and did shit all about it.
