Marcus is immediately suspicious, Ethan panics about hosting someone unplanned, Danny tries to be polite, and Lena insists they give the stranger a chance. As the night goes on, the guest overstays their welcome, eats their food, and disrupts the group’s routine. The roommates must work together to reclaim their space without causing a scene, ultimately realizing how much their home—and their friendship—means to them.
