Accidently knocking over the tall jar as she walked past, Donna gasped as the contents spilled onto the grated floor.
'Oh, he's going to kill me' she thought, knowing full well The Doctor wouldn't, but she was anticipating a horrid reaction from him.
She stood there for a moment, staring at the spillage, about to get a mop, when the Doctor rushed in.
'What happened? I heard a crash!' he exclaimed. Peering at Donna's shocked and possibly guilty expression on her face, he followed her gaze to the spillage. He frowned.
'Oh no' he murmured. 'What happened?!'
'It was an accident Spaceman, you know they do happen!'
The Doctor strode over and picked up the object that was laying in the middle of the liquid.
'Let's get you back into a new jar shall we?' he cooed to his spare hand.
