Apple’s Disclaimer episode 6 hints at what may have actually gone down between Jonathan and Sasha in Italy, which could completely flip the script on Stephen’s revenge plan against Catherine.

This was the planted seed in an elaborate attempt to ruin Catherine’s life for allegedly causing Jonathan’s death by drowning.
