Narrator: Buster’s girlfriend Lucille Austero, suffers from chronic vertigo, which she has been trying to fight without the use of medication.
You can see Lucille 2 stumbling and keeling over in her hallway ... which is decorated in a "boat cabin" style.
So it seems like she's being thrown around in a storm at sea : vertigo = balance disorder + nausea.
The scene even ends with Lucille 2 steadying herself by grabbing a boat wheel hung on the wall.
Did anybody else notice that ?
