I agree, the Fraser mystery was bad and also pointless.
The GHK would be better if they weren't giving us so many false clues, they just seem to be showing blue gloves for the sake of it. I liked Tegan's creepy goodnight to Esther, that is what they should be doing more of, strange behaviour rather than blue gloves.
And if Celine isn't the killer I would like to know what 'bad things' she has done (apart from stealing the painting), because if she isn't the killer I hope they didn't just make up that line for a false lead and there is actually a point to what she said.
And I agree, the killer should have stuck to killing bad people if that is what they started with, moving on to killing anybody has spoiled it slightly. I would also like them to mention extras being killed off rather than it just being main characters to make it more realistic. I also want the police to figure out someone is killing in the hospital, so they are investigating while the killer is still working there, that could be dramatic if done right.
I hope Kim dies, I have had enough of her. She is playing everyone and she can't get away with that, when two of the people she is playing are gangsters.
