While Drill loses strength, all of the children he has contacted are becoming ill. Thinking they might actually be able to defeat this unseen foe, Wes convinces the President to let him round up all of the children in a protected zone in the hopes that Drill will wither and fade away. Meanwhile, one of the team mourns the loss of a love one.
Wes meets with the President of the United States to discuss what his team has discovered about a mysterious object that may pertain to Drill. Meanwhile, Sean faces a possible prison sentence for his collaboration with Drill, and Lena attempts to communicate with Drill, with the help of daughter, Minx.
Claire speaks with Sean, who has no memories of her or their life together, and tries to get him to remember something…anything about his past; Wes has an epiphany and heads back to Mali to take another look at the fulgurite, and Lena keeps a watchful eye on Minx to make sure that her conversations with Drill have ceased.
