A little bit of harmless fluff.

'I reckon I could get you in check mate in five moves.' Harry announced as the Doctor gazed at the chess pieces. His eyes showed deep conerntration as though he were trying to get the pieces to move by using only his mind.

'Oh shut it Harry!' The Doctor replied sharply, 'You're ruining my concentration.' Sarah had to stifle a laugh from her position in the doorway. They acted like children, the pair of them, even if they would never admit it.

The Doctor sat up in bed, his right arm in a sling. He looked just as hyper as ever and it had been hell trying to convince him to stay in bed. But with a broken collar bone he simply wasn't going anywhere. Sarah had known something hadn't been right when the Doctor had been fighting the Sontaran.

Turned out he'd broken it long before that.

'Are you ok Sarah?' He asked from his place on the bed.

'Fine.' Sarah replied before busting out laughing as Harry and the Doctor started arguing again.

'You two are such children.' Sarah managed between large gulps of air.

'Are not!' They chorused back.

'Are too!'

'Are not!'

'Are too!'

'Sarah please shut up you're disrupting our friendly game of chess.' The Doctor replied, his blue eyes showing the amusement he was getting from this tiny argument.

'Ok.' Sarah sat down beside them and watched as they played. The Doctor had Harry in check mate in five moves.

'See, I beat you in five moves!' The Doctor exclaimed.

'It's not fair!'

'It is.'

'Is not.'

'Is too!'

'IS NOT!'

'IS TOO!'

'Have a jelly baby Harry!' Sarah left them to fight, reminded Harry that the Doctor was still healing and deciding that she badly needed a tranquilizer gun to keep them under control.
