Sebastian Blake (formerly Fox, previously "Sean") is the son of Sienna Blake and Warren Fox, twin brother of Sophie Blake and half-brother of Joel Dexter, Ella Richardson, Nico Blake and Maria-Gabriella McQueen.
A few months after being released from prison on legal technicalities, Warren Fox began a relationship with Sienna Blake. The relationship turned sour and the pair split, but Sienna discovered that she had fallen pregnant with twins in April 2017. Sienna was later diagnosed with cervical cancer, but decided to delay treatment until after she had given birth to the twins.
In November 2017, Warren ended up warring with gangster Glenn Donovan, and held Sienna captive in a safehouse. Sienna went into labour and Warren attempted to stop her from going to hospital, resulting in Sienna telling Warren that she no longer wanted him in her or the twins' lives. Sienna gave birth to a boy and girl, naming them Sophie and Sebastian. Warren kidnapped Sophie and fled the village, with Sienna raising only Sebastian.
After discovering that her daughter Nico Blake had survived a fire in May 2018, Sienna was stabbed by Nico and, with the help of Josh Bradley, faked her death so that Nico would get caught at her funeral. News of Sienna's "death" reached Warren, who returned to the village for Sebastian. Despite discovering that Sienna was still alive, Warren took Sebastian and returned to Sophie.
By July 2019, Warren and the twins relocated to Spain and hired au pair Nina Robertson. Nina took the twins with her when holidaying in England, staying at the hotel where Maxine Minniver and Damon Kinsella were due to marry. Sienna recognised the twins but Nina convinced her that they were not her children, with Warren firing Nina as he took them back to Spain.
Sebastian and Sophie returned to Hollyoaks with Warren in January 2020 after Sebastian fell ill and was diagnosed with leukaemia. Sienna proved to be a match, but was disallowed from donating bone marrow due to undergoing chemotherapy for cervical cancer. Warren lied to Sienna that Sebastian was being cared for in a private hospital outside of Chester (when in reality he had been admitted to Dee Valley University Hospital), and when Sienna found out the truth, she kidnapped Sophie and Sebastian and fled the village. Sienna returned with the twins in March 2020, having found a donor for Sebastian. The transplant took place a few days later. In July 2020, the doctor informed Sebastian's family that the transplant was successful.
After Sienna and Warren decided to put the past behind them, the pair decided to co-parent Sophie and Sebastian. The pair primarily lived at 5 Oakdale Drive, Flat 1 with Sienna, with Warren occasionally having them stay with him. In April 2022, a fire broke out in Warren's flat after he passed out with the oven on, with Sophie waking Warren before the trio evacuated. In March 2023, Sophie was involved in a car crash with Sebastian, Warren and grandmother Norma Crow but escaped without injury.
