The latest Solo: A Star Wars Story movie clip revealed Friday expands on a brief exchange glimpsed in an earlier trailer: One where Han Solo (Alden Ehrenreich) learns that his new BFF Chewbacca (Joonas Suotamo) is 190 years old and looks great (for reference, Wookieepedia says Wookiees have an average lifespan of 400 years).

Now we know the moment comes as Han and Qi'ra (Emilia Clarke) are piloting the Millennium Falcon around space rocks while a TIE fighter pursues them. Han asks for power to be diverted to the "rear deflector shield" and Chewie immediately goes to work, surprising Han who wonders how the Wookiee knew how to fly.
