Generally I'm with this meta, talking about how it's mostly regret he feels [over a - partly - misspent life] and how Eleven is the answer to this: Someone who lives fully.


Yes, that's so true, isn't it? You get the feeling that in between what we see of Eleven with Amy and Rory (and even River) there are vast swathes of adventures rather like the ones hinted at at the very start of Impossible Astronaut. You can never think of Ten alone without worrying about him, but Eleven will be popping up under some lady's skirt, or fixing up a child's dream bedroom somewhere.
