• Their participation is motivated by Mark's late wife and Margo's sister, Julia's, 'last wishes'.
• While in Greece, they were offered a ride to a bus station by a driver named Nomi.
• Nomi revealed her mother died of cancer three years prior, mirroring the circumstances of Mark's wife's death.
• An additional connection was discovered as Nomi's mother was an architect, the same profession as Mark before his retirement.
