The Ringer - S1-E1
Continuity mistake: The shot where the birds fly up to the castle shows that the tower Link is in has windows. There is one visible towards the top, and a few more on the second level. Later, when Link whistles at Zelda, it shows another exterior view of that same tower with Link in the top window. Now there are fewer windows on the lower level. (00:01:00 - 00:01:50)
