The episode concludes with a major forensic update: blood found under Dylan’s fingernails is a match for Holly, making her a prime suspect in her brother's murder.
CCTV footage from the train station shows Holly with a man whose face is obscured, but his distinctive white trainers with a red stripe point toward her uncle, Ryan Foley.
Following the recovery of Holly’s backpack from the sea, police find a significant amount of cash—roughly £8,000—which raises questions about where the teenagers got the money.
