I adored the storyline with Gates and the family where mother is brought in with liver damage and she is dying. Gates treats her and starts to suspect that this might be suicide. After taking with one of her sons he starts to understand the reasons behind her act and why and so when she is crashing, he is not rushing to save her and he has some talking with Luka to do. And the ending.. when Luka goes and changes the paper as he feels something to the case too. What was right? What was wrong.. and when we think this is solved the last talk with Gates and the son change everything again.
And then ofcourse the donor transplant the money involved. The choice Dubenko makes and what Neela does.
I love the writing of this episode - those cases, the questions risen.
