Lisa Swain — Becky’s official wife or longtime companion (depending on the script) — can’t stand aside now.

She begins to suspect, begins to investigate.

In a notable spoiler-worthy scene, Becky hands Lisa a flash drive containing a recording of Bernie talking to a stranger — saying that if Theo doesn’t suspect, she’ll release the file.

Lisa, heartbroken but determined, promises Becky to keep it a secret and wait for proof.

But trust isn’t always strong enough. Lisa, in a fit of torment, takes the flash drive to the police station — showing CCTV footage of a strange car stopping in front of Becky’s house at dawn. The scene makes Lisa angry: “Why didn’t Becky tell me?” she screams, holding up the USB, her eyes a mix of suspicion and pain.

When Lisa brings up the CCTV against DI Costello’s complaint — that Betsy once vandalized a police car — Lisa decides to use Becky’s evidence to counterattack: “I’m looking for the truth, and I’m not letting other people decide for me.” The Lisa-Becky confrontation might unfold in a dark office: Lisa asks bluntly: “Becky, are you hiding anything from me?” Becky shakes, eyes red: “I want to keep it all to protect you, Lisa…”

A climax: Lisa turns on the CCTV screen at the police station, showing the suspect car in front of Becky’s door — that image is spliced ​​with the recording from the flash drive. The security staff turn around — everyone looks at Becky, at Lisa, at the file — and there’s a tense silence. Will Lisa choose to compromise with Becky or believe the black and white evidence? Will their relationship unravel under suspicion?
