In this fan-fiction of Doctor Who, Martha has been killed by an alien villian three months ago, and the TARDIS is malfunctioning, appearing in the most random places. When she appears in the occuppied restroom of Tyler Singleton, scaring her half to death in the middle of brushing her teeth, none other then the Doctor himself appears ironically just in time to save Ty from a very angry gladitorian, and ends up having to take a very reluctant Ty along to save her life.
