Along with the partygoers, the clown is dressed up for a surprise birthday party for the anxious refugee.[1] The partygoers have not been very secretive about it, however, and the anxious refugee has heard rumors about it.[2]
The clown carries a knife as part of his costume because the partygoers found several pre-Warmovie posters, and saw that the clowns always held knives.[3]
↑Vault Dweller: "I'm sorry. I didn't mean to scare you." Anxious refugee: "No, I'm sorry. I shouldn't have reacted like that. I'm... really on edge lately. I hate surprises and I suspect my friends are planning something for my birthday. Maybe you could help me. Do you think you could investigate and see if they're actually planning something? All I need is a photo of the evidence. Out there, I don't have a choice. In here, if I can avoid being spooked I'm going to avoid it. I just want some part of my life to feel in control!" (Anxious refugee's dialogue)
