Just Be Kind
Doctor Who Season 10 Episode 12, "The Doctor Falls," was the beginning of the end for Peter Capaldi's fun as The Doctor. Opposite him, not one, but two, versions of The Master. In context, The Doctor had just spent seventy-five years trying to rehabilitate Missy, and it seemed to be working until this little outing. Her previous incarnation did not share any of her new beliefs and wasn't shy about letting The Doctor know it. Which prompted The Doctor to set him straight. "Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because....because I want to blame someone. It's not because it's fun and God knows it's not because it's easy," he says to The Master. "It's not even because it works, because it hardly ever does. I do what I do because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind."
I Believe In Love In All It's Forms
The Doctor is great at taking ordinary people and making them feel extraordinary. That's exactly what she did on Doctor Who Season 11 Episode 6, "Demons of the Punjab," when she officiated a wedding between Umbreen and Prem who become the first couple married in Pakistan. In an episode that was about what divides us, the Doctor offers a few empowering words: "‘You both found love with each other. You believed in it, you fought for it, and you waited for it. And now, you’re committing to it, which makes you two right now the two strongest people on this planet. Maybe in this universe."
I'll Never Forget One Line of This
No matter how many times you watch The Doctor regenerate it never gets easier. This meta speech at the end of the Doctor Who Christmas Special, "The Time of the Doctor" kicked us right in the feels when the Eleventh Doctor took his bow emphasizing the show's fifty years of history. "I will not forget one line of this, not one day, I swear. I will always remember when The Doctor was me..." he says.
Have a Fantastic Life
The Doctor will always put himself in harm's way to save his companions, and that's exactly what the Ninth Doctor did to Rose Tyler during Doctor Who Season 1 Episode 12, "Bad Wolf." Activating Emergency Program One, he sends The Tardis and Rose home, giving her instructions to go home and let the Tardis die while he fights a battle on Satellite 5. "And if you want to remember me then you can do one thing. That's all, one thing. Have a good life. Do that for me, Rose. Have a fantastic life," he says in a holographic recording.
Every Doctor gets a moment to make an entrance and defend Earth. For the Eleventh Doctor is happened at the end of Doctor Who Season 5 Episode 1, "The Eleventh Hour," on a hospital roof after stealing clothes from a locker room. He calls the Atraxi back to Earth and tells them off, ending with a very curt introduction of, "Hello, I'm the Doctor. Basically, run!"
It's All Untested
Even The Doctor has an identity crisis at times. When Christopher Eckelson regenerated into David Tennant it was the first time new fans of Doctor Who got a chance to see a regeneration. The Doctor spent most the Doctor Who Season 2 Christmas Special, "The Christmas Invasion," in the Tylers' apartment in a healing coma, springing to life for a few moments at a time. When he finally wakes up for real, he has some explaining to do, which is difficult when you're a new version of yourself. So when the Sycorax asks him who he is, the only logical response is, "I don't know." Followed by a lot of questions.
