Tonight marks the start of the second half of the first season of the terrific Under the Dome, and they are not holding back. I love that this series gives us a new reveal every week. A new “but what about this?” that gets asked and addressed, and sometimes answered. Last week it was “What about water? Crowd frenzy?” Answered, and addressed.

According to the clip below, this week we’ll also get a cool new mystery. Check that out, after watching the fun featurette that asks the cast how they’d react if they were in their characters’ situations, and a nice little YouTube video ostensibly made by teen Joe. Then there’s the TV spot for tonight’s episode, and that intriguing clip:
