Maybe he rode all the way to King's Landing cause he heard that guy had a monster dong.

They should have got the same guy that played Uncle Benjen to play Daario

I think Aemon saying he grew up in King's Landing was more of a zinger than exposition, saying he can spot a liar because he grew up in a city full of liars.

I thought Lord Tywin commenting how Ice was "absurdly large" was great, it's like he has those glasses from They Live and only he can see how impractical some of the weapons in Westeros are.
