The Doctors coat had many pockets, Donna knew that for certain.
She also knew that those pockets were bigger on the inside, the Doctor had explained it, Time Lord technology.
In his pockets she had discovered a range of objects, all found on her hunt for a pen.
She came across a wind up mouse, that Spaceman's sonic screwdriver, his psychic paper, a TV remote control , and oddly enough a spare pair of pyjamas, pin striped.
When she pulled out the paper bag of jelly babies , the Doctor came into the room and upon noticing the bag of sweets, he grinned. He picked them up from the table and offered it to Donna.
'Would you like a jelly baby?' he quipped , beaming away.
