Riley Vashtee
From Tardis Wiki, the free Doctor Who reference
Riley Vashtee was a crew member of the S.S. Pentallian, a ship mining from the sentient star Torajii. Shortly after Martha Jones arrived onboard with the Doctor in his TARDIS he develooped a strong attraction to her. While trapped in an escape pod and thinking they would both soon die in the fires of the star, Martha reciprocated Riley's sentiments in what they thought was there last minutes together.
The Doctor having rescued them, though, Martha departed in the TARDIS with the Doctor, leaving Riley to his life on the S.S. Pentallian. (DW: 42)
