I haven't had a chance to read everything on this thread but a couple things that stick out to me.
I'll start with
Tanya. She cut her hair. You can do long term testing by testing your hair.
Datu "feeling" himself changing.. He also thought he was dying from shock after The waterworks incident. Can't put stock in it.
CJ knowing everything about everyone. I think she did this just in case
Saul and
Victor tried to say she didn't care about coming to save them from
the mallers. However, getting to know people would have changed her.
Had a couple more thoughts but g2g
