Shaun Temple
From Tardis Wiki, the free Doctor Who reference
Shaun Temple was in a relationship with Donna Noble in the year 2010. The Doctor saw him and Donna shopping on Christmas Eve. Later that day, when the Master walked into the Immortality Gate, he took over Shaun and made him into another Master. After Shaun returned to normal, he married Donna the following Spring. On the day of his wedding, he was unaware that the Doctor had given Donna a winning lottery ticket, securing their financial future. (DW: The End of Time)
