Joan: Okay.

You're not in a snit, are you?

Jack: No, I'm not in a snit.

Sleep tight.

Cass' regulator was tampered with, which means she would've run out of air well before you would've expected.

Joan: You mean someone sabotaged it?

Jack: Brad didn't confuse her hand signal.

He ignored her.

But why?

Because he knew she would run out of air?

♪♪ Hold on, mate.

This won't take long.

We wondered how Cass ended up with your regulator.

Brad: Because my reg was top-shelf.

I thought she'd feel more comfortable with it.

Jack: And you gave it to her just before you went in the water.

Brad: Yeah.

She was nervous.

Joan: Who else had access to the gear before the dive?

Brad: Everyone.

It was stowed outside on our balcony.

Jack: You didn't tell the police about the swap?

Why not?

Brad: Hey, my wife almost drowned.

It's not really a detail I thought was important at the time.

I... ♪♪ Wait a second.

You think someone did this to her deliberately?

Joan: Or to you.

How would they know that you were going to lend your regulator to Cassidy?

Okay.

Nicola: Look, I despise the guy, but Cass loves him.

If I hurt him, I'd be hurting her.

Jack: Yeah, but you did a lot of dough on that franchise.

Nicola: This is ridiculous.

I'm a high-school art teacher.

Why would I -- Jack: Yeah, but you're an expert diver, you had access to the gear, and you've got a bit of a temper.

Nicola: Exactly.

So piss off.

And take your... accusations with you.

[ Bells jingle ] Jack: If Nicola wanted Brad dead, she's the type of girl to just walk up and shoot him point-blank.

Joan: What if nobody was supposed to get hurt?

What if the tampering was just something that an experienced diver would've easily fixed?

Jack: Those boys like a prank.

"Pirates of the Caribbean" beard, anyone?

Pete's a good diver, though.

Joan: That night before the dive, the -- the footsteps that I thought I heard... [ Clanking ] Maybe that was Pete accessing the gear.

Makes sense.
