I know from the show that Clara clearly shown to have a crush on Eleven
But in what episode was it ever shown viceversa?
You gave me a link to “The Name of the Doctor trailer" that showed me what I so in the trailer back when I saw it first,
I’m not sure which part your referring too, so I’ll answer them all, this is what I see:
Eleven show a great curiosity towards Clara, gratitud towards Clara, a sense of admiration (she’s the perfect happy go lucky person I need in my dark life), he say “my Clara” he did that with Pond too, he has always needed a companion even Donna said that (and Eleven doesn’t say it in a loving voice but serious way) so that’s not new, the way he says "to perfect" is in a way that makes me think like he’s dying of questions that he thought he’d never know the answer to, but then at the end shows that he never expected and never hoped what happened in the name of the doctor and hints that what Clara is, is dark somehow.
So I have a hard time seeing what you mean but maybe I missed something.
Truly hope to hear a response.
