Meanwhile, the military has scheduled a "visitors' day" for the residents of Chester's Mill, where family members and friends of people trapped in the dome can come and visit their loved ones.
During the event, Linda tells her fiancé about his brother's death, Norrie meets her estranged biological father (Gary Weeks), who her parents had led her to believe she would never be able to find, and Barbie finds out from a soldier stationed outside the dome that the military plans to attempt to destroy the dome with a missile (MOAB), which will likely kill everyone inside.
When Barbie relays this to Big Jim, he orders everyone to take shelter in the tunnels underneath the city.
As Big Jim investigates the edge of the dome, he is approached by Reverend Coggins, who earlier gave him an ultimatum to admit his part in a drug scandal to the town.
Jim kills Coggins by pressing his head against the dome, causing his hearing aid to explode.
