When Azkedellia plays back the message meant for DG at Finaqua, there was no mention of, "that is why she doesn't know of my plan."
Azkedellia has lost one of her tattoo monkeys, leaving her with six. When she sends out the monkeys to find her father, we see those six emerge from their tattoo forms - but when we see them fly away, there are clearly eight.
The garden house has been completely destroyed and is nowhere to be seen. But when DG throws the "perfect stone", the garden house is suddenly there, scorched and aged, before the country begins to change, then takes its original form.
DG was standing right in front of Azkadellia when the latter threw her from the tower. In the wider shots from the right side of Azkadellia we should see DG trying to climb back. There is no trace of her, as if she was to the left of Azkadellia. But again, DG climbs back right in front of her sister.
When DG is in the hut with Ahamo and is examining the compass, she is holding it in her left hand. In the long shot that immediately follows, she is holding it with both hands.
In several shots, the two suns are pictured in the sky with a full moon midway between them. However, in this position it should be a nearly invisible new moon, with the side in shadow facing the observer. The astronomy of this fantasy world may not be governed by the same rules as in ours.
Throughout the episode, a full moon is shown in the sky. Approaching and during a solar eclipse, there is a new moon because the sun is behind the moon lighting the back. The astronomy of this fantasy world may not be governed by the same rules as in ours.
When Azkedellia arrives at Finaqua to see what message DG received from their mother, she retrieves the "perfect stone" from the lake in order to skip it again over the water. However, you can see the stone is already in the actress' hand from the time she first steps onto the gazebo. She merely raises her hand and pretends to catch the stone from the lake. Evidently there are no pockets in that form-fitting outfit.
When DG is in the hot air balloon with Ahamo, she speaks the line "...by letting the old witch escape" but on the left side of the screen DG's mouth is visible and not moving.
When DG is in the hut with Ahamo she sits and examines the compass. Sound stage lights can be seen reflected in the glass of the compass, rather than the expected daylight coming through the opening at the top of the hut.
The gauges in the tower show manufacturer's marks. "Canadian Westinghouse Co Limited, Hamilton, Canada" "GE" "Weston Ammeter Made By Weston Electrical Instrument Company, Newark, NJ, USA"
