Just finished watching this episode and wow, I thought after all the programs and films that have covered the second world war, I couldn't possibly cry at a mention in a crime show. I felt rather reassured that Mac's eyes were red at moments in the episode, made me not mind so much that mine were watering too. Those interviews really got to me, and the bit near the end where mac was yelling at him to just admit it already, I swear it took a lot of concious thought not to do the same thing and I'm not one who makes the habit of communicating with inadimate objects. That moment with the flashback of the family has entered into one of the most heart breaking things I have seen on television, and I think they treated the whole thing very sensitively. I'm not sure its a episode I could bear to watch again, but it was very well done. And aside from the big theme, I loved the family fix from that scene with Danny and Hawkes at the beginning.
