The Lodger

The Tenth Doctor lands his TARDIS in present-day London, but before Rose Tyler can emerge, the TARDIS dematerialises because the Doctor forgot to lock the time settings. The TARDIS jumps a time track and moves ahead several days. Left stranded in London while he waits for Rose to catch up — only a few seconds will have passed for her — the Doctor needs somewhere to stay. After an aborted attempt at visiting Jackie Tyler, who is occupied with one of her suitors, the Doctor decides to crash at Mickey Smith's flat, where he proceeds to be a less-than-welcome houseguest for Mickey Smith. Meanwhile, a Bandrigan fleet approaches Earth with plans to destroy it.
