Plot summary
Desperate to stabilize himself before he is completely drawn away, Wilkes designs a containment chamber for himself, but requires more Zero Matter. Carter realizes that Frost is now the only source of Zero Matter, but is still too injured to get it herself. Instead, she breaks Underwood out of prison, sending her to one of Chadwick's campaign events with Jarvis. The event is also cover for a Council of Nine meeting, with Chadwick having convinced them to see Frost (they usually never speak with outsiders, let alone women). Masters and Thompson are also at the event; Jarvis distracts Thompson while Underwood collects the Zero Matter from Frost using a device designed by Wilkes.
Sousa tells Carter that his fiancée left him due to his supposed feelings for her. Underwood eavesdrops on the Council meeting, watching as Chadwick betrays Frost and has her restrained. Frost destroys Chadwick and half of the Council, proclaiming herself leader of the remaining Council members. Masters and Thompson capture Underwood for Frost.
