The image depicts four characters -- most likely Big Jim Rennie (Dean Norris), Junior Rennie (Alexander Koch), Sheriff Linda Esquivel (Natalie Martinez), and Barbie (Mike Vogel) -- staring at a sea of metal objects that have attached themselves to the outside of the dome, including grills, bikes, road signs, and lawn equipment. Though it's unclear just what exactly this new development means for those trapped inside the mysterious forcefield, we can't help but think that living under a giant magnet probably isn't good for one's health.
Speaking to that latter point, showrunner Neal Baer teased some devastating developments. Variety's Debra Birnbaum reported that Baer said "another beloved character will meet an untimely death" sometime in season two. Whether it's any of the four people pictured in this teaser remains to be seen.
The second season of "Under the Dome" premieres on CBS on June 30.
