It seems odd that the upon discovery, the move is to 'take a picture' as my sister is cheating on her boyfriend. There are a few things I suppose can happen from here:
- Salma takes the picture and shows it to their mother, where Farrah will as a result be placed on lock down.
- Salma uses the picture to coerce the masseur into having sex by threatening to expose Farrah's infidelity.
- Salma takes the picture and confronts Farrah with what she discovered, and they have a heart to heart. Farrah explains the details of how she and the masseur started their sexual relationship, and Salma, curious, proposes that she joins in, much to Farrah's protests.
- Salma takes the picture and shows it to Yousef, forcing a break up since she doesn't like Yousef all that much.
- Salma takes the picture and shows it to Yousef because she's masking an attraction to him, and takes the opportunity to start something with Yousef.
I hope the 3rd one plays out, but honestly knowing Max's style, I can see it being any one of these, or even a number of them put together.
