“The Well” is the third episode of the 15th season of the new “Doctor Who” series, also indicated as season 2, and follows “Lux”. It’s available in the UK and Ireland on BBC channels and in many other countries on the Disney+ platform.

Beware that in various adverts and marketing materials, this season is promoted as season 2 passing through a new start with the production by Bad Wolf and distribution by Disney+, hence the double notation.
