Another thing worth exploring is that Rick is removed just fine, but after Ben's harness comes off in "Silent Kill," the other five kids' vital signs in the room begin failing. Is there some sort of connection or chain reaction that destroys the group? Rick's co-workers are executed, so there is no chance to observe the effects on them. But perhaps separating the kids before performing the surgery will decrease the fatality rates. Or possibly there is little time to save the rest of the group once one kid is removed. The questions to ponder are nearly endless.
There is a lot of detailed technical discussion about these harnesses, and it is quite imaginable that most viewers do not care about the device one way or the other, but only how it emotionally affects the kids' friends and family. So enough of the technical stuff, and on to pathos!
There is plenty of emotional turmoil in "Silent Kill." Much of it concerns Dr. Anne Glass. She is torn about killing an alien hostage who kills a fellow doctor. She is upset about the kid she loses. But these are symptoms of her deeper grief, which stem from her son's death, and having nothing to remember him by. Anne has a very harsh reaction to having a child die on her watch because it sparks bad memories, and she feels incredibly guilty about her lack of photos and momentos. If only she hadn't gone to work, she would have either died with her family, or helped them escape. But they'd be together. No wonder she is having a rough time. Kudos to Ms. Bloodgood for the incredible way she is handling the role.
Tom has similar regrets in Falling Skies, as his wife was not supposed to work the day of the attack, prior to the series's start. Yet, she did, and so she died while Tom and their sons live on. Because of this, especially, Tom finds it hard to put his children in danger any more than he can help it. Unfortunately, he is unable to do much to prevent the threats. Ben has been a hostage for awhile, and Hal and youngest boy, Matt (Maxim Knight), are itching to help the resistance army. Matt is little enough he is satisfied assisting with the radio, but Hal is in on the action. Which is why it must almost kill Tom to let Hal go into the hospital by himself in this episode, an incredibly risky plan that is barely lucky enough to work.
