That's okay, I'll go with it. Under the Dome has 13 episodes to pad out events until it gets to the real meat of the series: what to do about the dome. Things aren't working out, the government doesn't know what's happening, and there's no end in sight to the problems these people will face. This is touched upon in "Outbreak," an episode that features the spread of meningitis throughout the dome thanks to the greenhouse-like effect caused by the entrapment of air. The residents of the Mill are finding out their resources aren't going to last forever, especially the medication that people need to survive.
But the show has continued to further relationships with its characters, especially Barbie and Julia. The main character has been painted as a heroic villain, a guy with a split personality of evilness and moralism. Before, it's been hard to tell exactly where he stands as a person - is he only playing the folks of Chester's Mill? Is he really the bad dude the show's been hinting at? We sort of get some answers in "Outbreak" and "Blue On Blue," or at least enough to provide us with some explanation until the real truth comes out.
"Blue On Blue," though, is a poignant episode about people coming together during what they believe is the end of their lives. As the town finds out that a huge missile is about to be shot at the dome, they prepare for the worst. They hunker down in the cement works hoping to escape the blast radius, but they also find that they have feelings for people that they might not have known before. Their relatives even come to visit outside of the dome for one last sendoff, an emotional moment that tries to involve even secondary characters.
Some big events happen in this episode, too. Finally Angie's released from her bonds thanks to Big Jim. Junior holds his own against a near riot and is rewarded by being deputized, to the chagrin of Barbie. Somebody dies. You can never say that Under the Dome is moving too slow, but it's always running a marathon race against itself. There's enough time in thirteen episodes to pack all of this in without rushing through events, but that's exactly what the show is doing in hopes of covering ground with character development. In a way, it's working, but it's also ensuring that viewers don't fully engage emotionally with the events.
