Verse: Doctor Who

Thomas Milligan was a doctor who worked for the NHS in 2008. When the Master brought the Toclafane to Earth he became a fugitive. In 2009 during the Year That Never Was, he met Martha Jones when she returned to England and took her to see Professor Alison Docherty. When the Master tracked them down, he used his laser screwdriver to kill Thomas.

When the Master's Paradox Machine was destroyed, undoing the Year That Never Was, and reversing time back to 2008, Martha phoned doctor Thomas Milligan, and then hung up, so that she could reassure herself in that in this timeline, he was alive. (DW: Last of the Time Lords)

When Martha, now working for UNIT, joined Torchwood 3 temporarily as a medical officer, she mentioned to the flirtatious Owen that she had a serious boyfriend. (TW: Reset) In fact, she had a relationship with "Tom", suggesting that she had initiated a relationship with Thomas Mililgan. (torchwood.org.uk)

She got engaged to Tom who is now a paedatrician working in Africa. (DW: The Sontaran Stratagem)

Changes made - Thomas remembers what happened that year, in the sense that he had many dreams and couldn't explain them.  The only constant in the dreams was Martha Jones so he sought her out and convinced her to explain everything to him and that is how they managed to grow closer and are now enbabed.
