No Eyelids

 Did he actually say that? asks Ageless.

Yes, says Terence.

Suggesting we'd be better off with no sea? asks Ageless.

He just doesn't know what it's for, says Terence.

What was said immediately before that? asks Ageless.

SOS, says Terence. No wait, SOC!

Now we're getting somewhere, says Ageless. What was the C for?

Now you're doing it, says Terence.

You have confused C with sea, says Ageless. They are two different things.

Sea and sea are the same things, says Terence.

But regarding SOC, says Ageless. What is its meaning?

Save Our Cuttlefish, says Terence.

I see, says Ageless, suppressing a laugh. 

What's so funny? asks Terence.

I said I see, says Ageless. 

You should go to sleep now, says Terence. 

So should you, says Ageless.

I don't sleep, says Terence. I can't close my eyes, can I?

Watch me, says Ageless.

He lies on his back.

I'm sleeping, says Ageless.

Your eyes are open, says Terence.

No eyelids, says Ageless.

Terence is impressed. Ageless is asleep with no eyelids. 

He makes a rude face, to test Ageless.

Ageless doesn't react.

Terence can do what he likes now.

He flashes the torch on and off through the lighthouse window.

SOC SOC SOC

One floor below, Gaius has woken, due to discomfort, and noticed a rhythmical flashing.

That will be Terence. He should go up the stairs and tell him to stop.

But the flashes are faint.

The torch battery is fading.

He goes back to sleep.

One floor below, Denis is reading a reply from Henriette.

Attached is a photo of the soles of her feet.

There is something written on each of them in very small writing.

What does it say?
