The query "Doctor Who season 2 episode 20" refers to an episode from the classic series, as the modern revival seasons have fewer episodes per season.
- The classic Doctor Who Season 2 (1964) had more than 20 episodes, but specific details about episode 20 are typically found in classic episode guides, such as on Rotten Tomatoes or dedicated fan sites
- The modern revival of Doctor Who labels its seasons differently. For example, the 2006 series called "Series 2" is actually the 28th season overall and contains 13 episodes plus specials, so it does not have an episode 20
- The current 2025 revival season, also called Season 2 (but of the new era starting in 2024), has only 8 episodes, so it also does not have an episode 20
Therefore, if you are referring to "Season 2, Episode 20" in the context of Doctor Who , it is most likely from the classic series era, not the modern revival. For detailed information on that episode, consulting classic episode guides or databases like Rotten Tomatoes for classic Doctor Who would be appropriate
