I really enjoyed last night's episode. I feel like it picked up all the threads from last year's episodes. I think it rings true that Fred & Joan would still be estranged after all that happened with her ex last season. As others have said, they are too alike and stubborn to admit they have done anything wrong so this will last a while. Really, Joan still has to face the fallout from the hostage taking because last season she was really avoiding it.
I felt really awful for Ruth Astor and everything she went through at the hands of the 'Beserkers', I wasn't really sad about any of their deaths. When Eve was speaking to Morse, she mentioned the convent school girl who tried to make it as an artist but didn't and ended up like her. I thought she was actually talking about herself but in hindsight it must have been Ruth right?
