The beauty of this episode was defenetly Susan's storyline - the way from the beginning of the episode we got those little clips of that old man, she has trying to help, preparing for their meal and how, from step to step he started to realize and that drown him into the point he pulled the trigger. Great camera work and very emotional.
Also, Gallant and his try to save that girl with cancer - again, very emotional and sad but well done.
I start to like Sam's son more and more even thought Sam's char leaves me totally cold. And Kovac and Elizabeth confronting each other - that was rather good either.
I think a great episode.
