So Grandma was inside everyone's head. She tried to come off as sort of sweet, but got a bitter look on her face when asked about Killian's son. In a Bette Davis moment, she uglied out, "He has no idea what went on".
I believe Killian's son has already said that he DID KNOW what was going on. I thought the father and son were both in the guard at the same time.
And Gary Killian said that for example, those memos directing someone to take a physical would not have come from Operations as this memo does, but from the Clinic.
I wonder why this particular memo didn't come from the Clinic as was the normal pattern...
I think Gary Killian knows just a bit more than she thinks he does.
