‘I had a very serious thought, just then,’ said Twilight.
‘Oh?’ said Smith. ‘Let’s hear.’
‘But I’ve forgotten it.’ And she looked so distressed that Smith couldn’t help but chuckle.
‘I’m sure it was a very good thought.’
‘It was! And now it’s gone! Poof, vanished!’
‘I’m sorry to hear it,’ said Smith. ‘What were you thinking about before you lost it?’
‘The tensile surface strength of magical plasmids,’ said Twilight, ‘but it was unrelated. One of those spontaneous moments of inspiration, you know?’
‘Mmhmm.’
There was long silence, before— ‘Aha!’
‘Oh? What was it?’
‘...I have absolutely no idea.’
