This is the first episode where Mulder actually kills someone. See more »


(at around 43 mins) Young Barnett is seen in the hospital with a bullet wound on his left shoulder, received from the shot fired at him by Mulder. However, his left shoulder was earlier hidden behind his hostage, so could not have been the target of Mulder's shot. Only his right shoulder was visible, which could have been the target of the only shot fired at him by Mulder. However, a shot fired at his shoulder could not have incapacitated him the way it was depicted, which could only have been possible with a shot aimed at his head. But, as seen in the hospital, his head was completely injury-free. Moreover, a shot fired at his shoulder should have also given his arm a strong backward thrust, which was not seen. See more »

Salamander Hand Man!
14 April 2006 | by (Roy, Utah) – See all my reviews

Young at Heart is another solid season one episode. I like the guest star character of Reggie Purdue and I liked the performance by the actor playing the young Barnett. What I thought was great were the phone conversations between Mulder and Barnett. Barnett has this cool, evil laugh that I can't describe in words. Another nice edition to this episode was Agent Henderson from the crime lab. She and Mulder exchange some double-entendres. Unfortunately, we do not see here again in the series. I think it would've been nice to have Agent Henderson pop up every once in awhile like Agent Pendrell does. I think Mulder's struggle with his past actions in this case for failing to shoot Barnett plays out beautifully. It certainly shows us how difficult it can be to be an FBI agent and the decisions they can face. The question is how Mulder will react when later faced with a similar crisis?
