The description made for this episode is actually for Shell Shock part 2. I enjoyed that episode even though waiting to see what happened with the story line is frustrating to any avid viewer. I understand the need to split the episode into multiple weeks when there is an important lesson to teach the audience that cannot be summed up in one week's airtime. And the issue of PTSD is a huge one that should be known by anyone that encounters a soldier. Anyone can help, it doesn't always take a lot, a few comforting words of encouragement from a stranger could be enough to convince a veteran to get help. I have not yet been able to watch the episode "Gone" but I am a huge fan of the series.
