Barbie takes a leap of faith on Monday’s episode of Under the Dome (CBS, 10/9c), and TVLine has an exclusive first look at his dramatic free fall.

In the sneak peek above, Julia and Rebecca watch as Barbie lowers himself into the tunnel’s abyss, hoping to see something other than darkness. But when the anchor holding Barbie comes loose, dropping him even further into the void, he opts to cut through his rope altogether and fall down, down, down — after sweetly declaring his love to Julia.

(You might also want to lower your volume toward the end, lest Rachelle Lefevre’s scream shatter any nearby glass.)
