Chapter 1. Mysterious illness.
'ROSE TYLER! If this carries on you are going to see a doctor! Right?'
'Yes.'
Rose really wasn't in the mood to argue, not today. She couldn't really hear what the doctor was saying either as she had her head stuck down the toilet for the 5th day in a row. She wasn't worried, she had always been sick as a child, she was used to it, it didn't bother her. What did bother her was her suddenly weird appetite. All the food she was used to eating when she as ill just made her throw up again at the very thought. Instead she was subjecting her . . . companion to torture with him making peanut butter and pickled onion soup! It was completely disgusting, though not that Rose minded; it filled her up and he still made it for her.
Said companion was worried. Humans' being sick and going off their favourite food for the most disgusting food combination imaginable was not a good sign. The excuse 'it was something I ate' didn't ease his mind, when he was as sure as hell it wasn't.
Not only that but her was stuck on Earth with the bloody-awful-sort-of-mother-in-law. Jackie Tyler was the limit – no – so far past it she just kept passing past it. She was forever talking and for the most part it was for the sake of talking. She sent the doctor death glares behind Roses back and made violent gestures that clearly said, 'I'm going to leave you here as punishment for eternity with no TARDIS when find out what's wrong!' he tried to keep out of her way but after 3 days of Roses illness, she insisted upon staying onboard the TARDIS. He only agreed for Roses sake.
Mickey was quite understanding and thought nothing more of it apart from a bug or something. He argued against Jackie (and survived, he doctor was rather surprised at this after their 'disagreement!') that Rose wasn't immune to everything in the galaxy and something obviously didn't agree with her. Fair point if she then didn't turn it against him arguing that he didn't have her daughter protected. When he told her even he wasn't immune to everything, she soon shut up.
With the promise to go and see a doctor the next day, both Jackie and Mickey left and with it came back the silence and peacefulness the TARDIS (and its occupants) preferred.
The news Rose brought back with her proved Mickey right to a certain extent, just a tummy bug. She was given antibiotics to clear it up. Jackie let her daughter go again not knowing the future. No one did – except Rose. For the real news she had would change everybody's lives.
