Settling into his home, Carl looks through Ellie's childhood scrapbook, and is surprised to find that she has filled in the blank pages with photos of their marriage, along with a note thanking him for the "adventure" and encouraging him to go have a new one. Reinvigorated, he goes to find Russell, only to see him sailing off with some balloons to save Kevin on his own. Carl empties the house of furniture and possessions, lightening it, and pursues him. Russell is captured by Muntz, but Carl manages to board the dirigible in flight and free both him and Kevin. Dug accidentally defeats Alpha and becomes the dogs' new leader. Muntz pursues them around the airship, finally cornering Dug, Kevin, and Russell inside Carl's tethered house. Carl lures Kevin back onto the airship with Dug and Russell clinging to her back, but when Muntz leaps after them, he snags his foot on some balloon lines and falls to his death. The house then descends out of sight through the clouds.
