At the beginning of the sub-quest "Lone Rumblings in Longwythe", Dustin goes to investigate the tremors alongside Monica and directs Noctis to receive briefings from her.
When darkness overtakes the world, Dustin escorts Talcott and Iris back to Lestallum. He remains on the move, delivering information between outposts.
