So in The Snowmen,ย Clara:

  • Persisted in following after the Doctor despite him pushing her away and being cold and dismissive.
  • Used her cleverness and curiosity as an impetus to get up to the secret staircase to the cloud, even dared to knock on his door.
  • Maintained faith and admiration in him despite being told over and over again that he didn’t help others, that he didn’t bother with the world any more.
  • Switched the paradigms on him quickly (hand-holding, running, plan-hatching).
  • Was fatally wounded and still maintained all of her cleverness and faith and admiration, agreeing to go away with him if he saved the world.
  • Brought him out of his depression and made him want to start traveling again.

In Time of the Doctor, Clara:

  • Persisted in following after the Doctor despite him pushing her away and lying to her.
  • Used her bravery and her determination to go back multiple times, clinging to the side of the TARDIS and being stuck in space and among the stars as the ship took her back to Trenzalore.
  • Was determined to be by the Doctor’s side on what would likely be his very last stand/sacrifice in battle regardless of the danger.
  • Was brought back to his side when it seemed likely he was going to pass away so he didn’t die alone, and was basically told that she was the only one that “could fly him.”
  • Oh and maybe sort of kind of a little totally told her family that he was her boyfriend.

In Last Christmas, the Doctor:

  • Persisted in following after Clara into her dream world, even though it meant he would have to slowly die to do it.
  • Refused to let go of her hand for half of the episode.
  • Pleaded with her twice to go onto the TARDIS/come away from him (the first for her safety, the second as close to an eloping proposal as you can get).
  • Was ready to kill the dreamcrabs for attacking Clara, regardless of all that SCIENCE! curiosity shaz.
  • Refused to let go of her hand for half of the episode.
  • Shared a dream world with her in which they both wanted her to have lived a long, happy, fulfilled life full of love — but where no one else came around that was good enough to share her life.
  • Learned that he was the only other person whom she ever loved like she loved Danny, and was subsequently the only other person that she could ever want to be with.
  • Said the most Nicholas Sparks-y line in the history of Who when he told her that she would never look any different to him, after an entire series where he’s made funny, strange remarks about her appearance.
  • Expressed regret that he didn’t come back for her sooner, not because she was old, but because those 62 years were years of her life that he missed.
  • Refused to let go of her hand for half of the episode.
  • Got a second chance at a new start with her.

On the scene between the Doctor and Clara immediately after the volcano in Dark Water:

I loved the scene. The acting is extraordinary and that is what I think has powered this series. Iโ€™m also proud of a line โ€“ Iโ€™m very rarely proud of anything I write โ€“ but Iโ€™m proud of the line โ€˜Do you think I care for you so little that betraying me would make a difference?โ€™ because I got obsessed when I started to write this that Cybermen have no emotion, so it starts with Clara unable to find a way to say I love you and ends with Danny unable to find a way to say I love you, there are two phone calls that book-end it, and in the middle, the cracked old Caledonian gets it exactly right, he says I love you perfectly. […]

Heโ€™s surprised he has to say it. Thatโ€™s the truth about him, he says lots of horrible things all the time, thatโ€™s because he assumes all the other stuff is taken for granted and itโ€™s only in that moment Clara realises just how much heโ€™s assuming is taken for granted, absolute monomaniacal devotion to her. He absolutely loves her.
