I love this episode, and think it is one of the best of the season. Seeing how Leo died so selflesslessly at Guadacanal was touching. And the fact that two men who he viewed as friends died there was sad. In times of war, people can be irrational. Nathan and Rick blaming Leo for their deaths, while, unreasonable, is still understandable. He was their friend, apparently so good a friend that they joined the army and requested to stay together. The brothers felt Leo should have placed their lives ahead of strangers. But Leo had done what seemed to be the best decisions. He stabalized his friend and left him to another medic(?) at the aid station. Then, with Rick yelling at him to stay, Leo ran out into the field to help the other wounded, only for the medical tent to be hit and blow up as he ran off. He must have been in shocking, having just watched his two best friends and heaven only know how many other die, but Leo followed his own advice to his charges: Find your stregnth within yourself. We know from his Medal of Honor that he died saving countless others. At the end of the show, when he and Piper attend the reunion, and so many veterans want to shake hands and meet Leo's "grandson", is one of the most beautiful moments of the series. These men have been waiting six decades to thank Leo Wyatt and thought they would never be able to thank him. But now they can and it will give many of them a closure that they would have lacked. Seeing all of them waiting to meet the "grandson" of the man who gave them and their families a chance at life was wonderful.
The side story of Cole/the Source was a good lighter side. Yes, the dark one himself was practically the comic relief. Julie was a neat new character, one that I wished could have stayed around longer. But as the Cole storyline winds down soon after, you know this is a soon to be vanquished demon. Too bad, so sad.
