The Ringer - S1-E1
Continuity mistake: As the camera pans over to Link asleep in bed, you can see his sword tucked under his pillow. His bed has no fitted sheet over it, just being apparently bare wood save for the sheet he's covered up with. It then cuts to a close up as he wakes up, and in frustration he picks his pillow up grumbling. His sword vanishes from under his pillow and now his bed has a sheet over it. (00:01:05)
