- Walter mulls things over and decides he has to confront Fosco that very night.
- He goes home and tells Marian what he plans to do. Marian is scared but says she's got his back.
- Neither of them tells Laura anything, of course.
- Walter also writes a letter to Pesca and tells him to open it in the event that something happens to Walter.
- The letter explains that the count betrayed Pesca's society and that the society can start with the whole tracking-down-and-exacting-revenge thing now, thanks.
