ichabod 5pts Ace Pirosu -- agreed! If you know some really, really bright people, you will recognize this Doctor's irritation from having seen them react similarly when they're feeling frustrated by the (comparative) slowness of others around them; also the tendency sometimes to poke sharp words and sharp ideas at others, to see if they're really keeping up and *capable* of that. I've seen this behavior in people with asperger's (went to school with them). IMO, what makes the Doctor's snappishness and irritability different from that is that he does it consciously and with intent -- even malice, sometimes, as well as with an edge of humor, which both indicate a capacity for empathy, however well suppressed or disguised. Hmm; as I guess you can see, I'm finding Capaldi's performance very interesting and impressive; stick around, lots to see here . . . including how long and how well it wears and how successfully it finds its older-than-adolescent audience.
