'And they're what you really need, are they?' said Rincewind.
'I'd plump for a bottle of really strong sun-tan oil,' said Bethan.
'Come on,' said Rincewind, and set off down the street. The others followed.
It occurred to Twoflower that some words of comfort were called for, a little tactful small talk to take Bethan out f herself, as he would put it, and generally cheer her up.
'Don't worry,' he said. There's just a chance that Cohen might still be alive.'
'Oh, I expect he's alive all right,' she said, stamping along the cobbles as if she nursed a personal grievance against each one of them. 'You don't live to be eighty-seven in his job if you go around dying all the time. But he's not here.'
'Nor is my Luggage,' said Twoflower. 'Of course, that's not the same thing.'
'Do you think the star is going to hit the Disc?'
'No,' said Twoflower confidently.
'Why not?'
'Because Rincewind doesn't think so.'
She looked at him in amazement.
'You see,' the tourist went on, 'you know that thing you do with seaweed?'
Bethan, brought up on the Vortex Plains, had only heard of the sea in stories, and had decided she didn't like it. She looked blank.
'Eat it?'
'No, what you do is, you hang it up outside your door, and it tells you if it's going to rain.'
Another thing Bethan had learned was that there was no real point in trying to understand anything Twoflower said, and that all anyone could do was run alongside the conversation and hope to jump on as it turned a corner.
'I see,' she said.
'Rincewind is like that, you see.'
'Like seaweed.'
'Yes. If there was anything at all to be frightened about, he'd be frightened. But he's not. The star is just about the only thing I've ever seen him not frightened of. If he's not worried, then take it from me, there's nothing to worry about.'
'It's not going to rain?' said Bethan.
'Well, no. Metaphorically speaking.'
'Oh.' Bethan decided not to ask what 'metaphorically' meant, in case it was something to do with seaweed.
Rincewind turned around.
'Come on,' he said. 'Not far now.'
'Where to?' said Twoflower.
'Unseen University, of course.'
'Is that wise?'
'Probably not, but I'm still going—' Rincewind paused, his face a mask of pain. He put his hand to his ears and groaned.
