LOS ANGELES, CALIFORNIA: Millie Gibson's return as Ruby Sunday in 'Doctor Who' Series 15 is now less certain. When Ruby Sunday first appeared in 'The Church on Ruby Road,' 'Doctor Who' quickly established her significant role in the story.

Ruby has been a central character, often as prominent as Ncuti Gatwa's Fifteenth Doctor, especially in episodes like 'Boom' and '73 Yards.' However, early 2024 reports suggested Varada Sethu would take over as the companion for 'Doctor Who' Series 15.

Amid this uncertainty, Millie Gibson's status in the 'Doctor Who' cast was officially confirmed by the BBC though a tweet on X in April 2024. She will join Gatwa and Sethu as part of a three-person TARDIS team, with the Doctor accompanied by 'two companions'.

Despite this clarity, the ending of 'Doctor Who' Season 14 raises questions about Ruby Sunday's future. After discovering her birth parents and finding closure, Ruby shares a poignant, tearful goodbye with the Doctor before the episode concludes.

Even though Ruby's storyline seemed to conclude in the closing moments of 'Doctor Who' Season 14, all signs point to Millie Gibson returning for Series 15.

Besides the BBC's announcement confirming the Doctor will have two companions in 2025, Gibson herself has mentioned filming the new season in interviews.

Moreover, Jonah Hauer-King has reportedly joined 'Doctor Who' Series 15 in an undisclosed role, sparking speculation that he may play Ruby's boyfriend, especially after scenes were filmed together.

These developments strongly suggest that Ruby Sunday's journey will continue, despite the emotional farewell with Ncuti Gatwa's Fifteenth Doctor. The unresolved mystery of Mrs. Flood's true identity in 'Doctor Who' Season 14's finale also hints at Ruby's future role.

Only Ruby's grandmother, Cherry Sunday, knows the truth about Mrs. Flood, providing a compelling reason for Ruby to reunite with the Doctor.

Ruby will not feature as the main companion in 'Doctor Who' Series 15

Millie Gibson's appearance in 'Doctor Who' Season 15 doesn't guarantee she'll return as the Doctor's traditional companion. In Season 14, her departure from the TARDIS is a poignant moment, leaving both characters in tears despite the Doctor's promise to see Ruby again.

If Season 15 begins with Ruby quickly changing her mind and rejoining the TARDIS, Season 14's emotional ending would lose its impact, possibly leaving viewers feeling misled.

One potential scenario is that Varada Sethu becomes the Doctor's main companion in Season 15, accompanying him regularly in the TARDIS. Ruby might instead take on a supporting role, remaining in her own time period but assisting the Doctor when he visits Earth.

Alternatively, Ruby could encounter a new threat involving Mrs. Flood or Jonah Hauer-King's character, prompting her to seek out the Doctor for help. This could lead to a reunion with the Doctor and an introduction to her successor.
