I can’t say how much I love this scene. Maybe because you can see the love in both their eyes, they have for each other.
This is Clara, the woman who is connected with the Doctor ever since. And he knows about that, knows how his life is interlaced with her and I think he cares so deeply about her not only because he owns her so much.
This is a relationship old as the hills. It is sometimes rough and bumpy and it is far the usual romantic relationship we know and we hope to see one day – this is something beyond. This is something special. And I am sure, there is no power in the universe, that will change that. What ever will come, in the end, this moment remains. Them. Together. Or not at all.
