Her new gift was a sonic screwdriver. Entranced, Romana stroked it. This decided matters. The Doctor's feelings must be very deep indeed.
Romana broke down and went to thank him. She found him in the library with K9 settled on the floor.
'Thank you, Doctor,' she said simply.
His head flew up from the book he was reading. 'What? And why do you have my sonic screwdriver?'
'This is the one you gave me,' Romana snapped.
'I never!' cried the Doctor
'Then who...' said Romana.
K9 waggled his tail. 'I love you, Mistress Romana.'
