What Doctor Who Season 15’s Trailer Reveals About Gatwa’s Second Season

New Mysteries & Reunions Are Inbound

The latestDoctorWhoseason 15 trailer gives a better glimpse of how Gatwa’s second season will unfold. As opposed to past companions who choose to travel with the Time Lord, Belinda seems to be aboard the TARDIS for reasons outside of her control, relying on the Doctor and his vessel to get her home. While it is a familiar dynamic that was seen with William Hartnell’s very first TARDIS crew in 1963, the Doctor immediately draws connections between Belinda and season 14’s Mundy Flynn, suggesting something more powerful may be in play.

After the shocking early debut of Varada Sethu in the Doctor Who episode “Boom,” many are eager to discover how what her role will be in season 15.

Another mystery for audiences is just how Ruby Sunday will play into the season, as despite the Doctor still thinking about her in “Joy to the World”, it remains to be seen whether they reconnected between seasons. Despite not working with the Doctor directly, past teasers and trailers have seen her working alongside UNIT and taking charge when monsters threaten a pub of unsuspecting civilians. As such, Ruby is clearly a more confident figure inthe wake ofDoctorWhoseason 14, but it remains to be seen how she’ll react to reuniting with the Time Lord.
