I laughed my butt off when I saw the good doctor in the crowd when Twilight tried to explain the visit from herself. I half expected to see him snooping around in the background making sure Twilight went back again to prevent a paradox.
I finished watching Doctor Who about a month ago and Twi telling herself where to find time spells reminded me of Time Crash special from season 4. [link] "You remembered being me watching you doing that. You already knew what to do because I saw you do it."
Oh that Wibbly wobbly Time-y wimey time travels, I love them ^^
