Rose Tyler lifted her right hand over her left shoulder and tossed the coin she was holding in her hand into the Trevi Fountain , Rome .It was May 22 , 1762 , and her and the Doctor had just attended the ingratiation of the newly complete fountain held by Pope Clemens XIII .

' Rose Tyler', started the Doctor , who was standing beside her on the edge , marvelling at the papal coat of arms of the fountain , ' you may have been the first person in history to toss a coin into this fountain . What did you wish for ?' he inquired , curious.

Rose turned her head and faced him .

' Does it need saying? It's the same thing I wish for every day . I don't need to toss a coin into the fountain to wish anything. '

The Doctor surveyed her face, she had her tongue between her teeth , a smile on her face

' To stay with you forever ' she told him .

The Doctor grinned back , he loved that smile of hers .

' Come on,' he tugged her hand . ' Lets visit the Spanish Steps . They aren't even 50 years old yet ! Allonsy!' as they walked off through the city , hand in hand.

Little did she know , two months later , when there was an army of ghosts , really cybermen , and Daleks , and she was pulled into the void , that wishes didn't always come true.
