Uh-Oh!

 Louisa is not unreliable.

She can't leave without telling Gaius, who is poking about in the distance.

And this is no good! Terence is heading off in a westerly direction.

But Arthur is already on his bike.

Wait, Arthur! calls Louisa.

Okay, says Arthur.

That was easy. Louisa runs over to Gaius.

Arthur and I are going to ride on ahead. Catch up with us when you're ready.

Excellent, says Gaius. Porntip and I have discovered a crop of redlichia.

Great! says Louisa. I remember the last time you were here, you were looking for redlichia.

Indeed, says Gaius. I was investigating a possible relation to the ediacaran biota.

So, you keep on doing that, says Louisa. We'll push on to the burnt regions. 

Remember to look out for Glossy Black Cockatoos when you get there, says Gaius. Note their numbers.

Sure, says Louisa. By the way, Terence is staying with you. He wants to.

Where is Terence? asks Gaius, looking around.

Heading down to the western end of the Bay, says Louisa. Towards the playground. I thought I'd better tell you, before he disappears out of sight.

Of course, says Gaius. Thank you. Hum. Someone ought to go with him.

Send Roley, says Porntip. He's not busy.

Who? says Gaius. Oh, Saint Roley. Where is he?

No need to ask. The back end of Saint Roley can be seen heading westward already.

Terence is slowing. The beach is four kilometres long.

He decides to flag down the next car.

A car is approaching, behind him. Terence waves his longest piece of orange peel.

The car stops.

Uh-oh! It's a Toyota Hi-Lux!
