I thought Alison(Sami) did a good job today, she was emotional & devastated(altho as a Rafe fan, I was happy he was there to support & comfort her). I don't read spoilers so I don't know how Sami is being written off the show: she & the children will leave town for safety, I guess.
And is EJ really dead? Some people are speculating that he will turn up at some point in time.
