After traveling over 5,000 miles in 45 days, the Roadtrippers reach Massachusetts for the final week of their journey. There, they meet with Jeremy England, an MIT biophysicist, and Juan Enriquez, the CEO of Biotechnonomy LLC. Change is the topic of discussion with Juan, who tells the Roadtrippers to 'scare the hell' out of themselves sometimes because stagnancy is the enemy of personal growth. Moving onto the last interview of the trip, the Roadtrippers meet with Lydia Villa-Komaroff, an internationally-acclaimed molecular biologist and Chief Scientific Officer at CytonomeST. Lydia discusses the challenges of being a Mexican-American woman in a male-dominated field, and credits her passion for helping her to overcome obstacles. Afterwards, the team heads to the airport where they reflect on their personal growth and future paths before sharing one last group hug.
