Pip waits at Romer Close until Ravi arrives, then explains that she followed the drug dealer from the station to the same road where Andie Bell’s car was found. Before showing Ravi the full discovery, Pip confesses that Sal’s police interview arrived weeks earlier and that Pip hid it because Sal’s evasiveness made Pip briefly fear Sal might be guilty. Ravi is hurt, but accepts Pip’s apology when Pip says she now understands Sal’s behavior differently.

Pip leads Ravi to Howie Bowers’s bungalow and points out Howie’s car: the registration is R009 KKJ, the plate Sal saved in his phone. Pip and Ravi infer that Sal followed Andie, saw Andie meeting Howie and dealing drugs, and argued with Andie because Sal hated drugs. Sal’s refusal to tell police about the argument now looks like an attempt to protect Andie, whom Sal believed was still alive, rather than evidence of a murder motive.

Pip uses photos of Howie selling drugs to Robin as leverage and forces Howie to let Pip and Ravi question him. Inside Howie’s messy bungalow, Howie admits Andie approached him in early 2011 with a plan to sell to schoolchildren for a cut of the profits. Howie gave Andie rules, codes, and burner phones for business, and says Andie hid the drugs and phone beneath a loose floorboard in her wardrobe.

Howie says Andie sold weed, MDMA, mephedrone, ketamine, and Rohypnol, including to a “posh kid” who may have been blond. Pip connects this to Max Hastings. Howie denies any romantic or sexual involvement with Andie, grows angry and defensive, claims he was passed out drunk the night Andie died, and insists Sal killed her.

When Pip ends the interview, Howie blocks the door until Pip deletes the incriminating photos, then warns Pip that dangerous questions bring dangerous answers. Once outside, Pip reveals she can recover the deleted photos. Pip and Ravi process the fear and adrenaline with jokes and laughter, while carrying away major new leads: Andie’s hidden burner phone, Howie’s feelings and behavior, and a possible Rohypnol link to Max.
