Okay the last episode was a complete turn around. the Doctor was working out a problem logically and is it just me or does he interact with children better then adults? When it's a child he seems to soften just a bit and his sternness comes off as him being protective and the way he explains things doesn't seem rude and hateful. Maybe what this Doctor needs is a younger companion who for some reason he can't take back to her home,that would be interesting and new and I think it would play to Capldi's strengths.

Any way this was my favorite episode of the season so far so I am hopeful that the next three will continue to improve.
