The way she says "I'm so sorry." Do you think we are meant to believe that people now suspect the truth about Norma's death?
shareI don't think anyone ever really knew what happened, but there would definitely be those close to the situation with suspicions. I took Emma to mean she was sorry for leaving Norma alone with Norman, and not being there to help her.
shareAt this point she knows Norman killed her own mom, so I don't think it would have been difficult for her to make the leap into considering that Norman killed Norma as well. Especially since she knew her and was quite close...obviously anyone is capable of committing suicide and people around them may not always know, but I think Emma was close enough to her to immediately suspect the suicide story.
But I think in general, the I'm sorry was just a blanket, I'm so sorry you're gone. I'm sorry for anything you went through. According to the dates on her headstone, she was 41. That's very young to die, regardless of the cause, so just about anyone would feel sorry that someone died so young.
