Chat with Liam on the Tempest after leaving Aya and he’ll give a suggestion regarding lowering crew tensions. This starts the quest "Movie Night: Getting Started". Head to the Bridge, access the Galaxy Map and return to the Nexus in the Zheng He system. Your goal on this visit - like most every visit to the Nexus - is the Operations level, where you’ll find an "Archive System" on the northeastern chamber of the central section. Nab the movies off the archives and return to Liam on the Tempest to put this quest to rest.
