Mark has tumor back but he does not share it with anyone except Susan who is taking care of her even though he doesn't want it. Elizabeth knows nothing and thinks that she has left Mark as she still blames him on what happened. She shares it with Benton (so great to see him back, even for moment and they still have best move he ever made in opening credits)
mm.. on the other storylines - nothing too impressive but everything good was represented - really moving and shocking cases like that little girl who shot his father as he said he will shoot her if she wouldn't turn the tv down.. so she shot first..
And Abby and Luka in the end.. beautiful episode.
