In a preview clip exclusive to Us Weekly, Vuolo and pal Luis Robles enjoy a barbecue with Jinger, Jessa and Jessa's husband, Ben Seewald. At the shindig, it is clear that Vuolo has a lot on his mind as he plans the perfect moment to ask Jinger to marry him. (As fans know, Jinger, 22, and Vuolo, 29, got engaged on a New York City rooftop in July after their brief courtship.)
"Jeremy is getting very excited as the day approaches, and he's trying to remain calm, though," Jessa, 23, tells the camera. "I don't think he's appearing anxious outwardly, but he's remaining very calm, so Jinger won't catch on."
Jinger says to the camera about her time in the Northeast to visit her beau, "Out of all the trips that I've taken in my life, I think that this is definitely one of the most memorable because it's been spent with my best friend, the most amazing person, gift from God."
However, Robles appears concerned that the pressure of proposing may be a bit much for his friend to handle: "What I'm nervous about is Jeremy — how he's gonna hold up, is he going to be able to keep a straight face the entire time, is he going to lose his mind, is he going to start crying halfway through the day because of pure joy and emotion? We'll see."
At the end of the clip, Jessa adds about her younger sister, "I don't think she has any clue what's coming."
