Adolescence was a difficult time for Grant, who observed that it went on for a lot longer. (TV: The Return of Doctor Mysterio)
Women who abandoned their children tended to be teenagers or in their early 20s, statistically. (TV: The Legend of Ruby Sunday [+]Russell T Davies, Doctor Who series 14 (BBC One and Disney+, 2024).)
The Doctor[]
The Tenth Doctor called the First Doctor a teenager, to which he objected. (AUDIO: Collision Course)
The Fourth Doctor recalled having been a "spotty teenager" for fifty years, (COMIC: Doctor Who and the Time Witch) while the Thirteenth Doctor remembered hot-wiring warp drives on the weekends when she was a teenager. The Thirteenth Doctor quickly noted, however, that there had been no weekends on Gallifrey, nor indeed teenagers. (TV: Ascension of the Cybermen)
