Long Live the Kings, Part II - S3-E19
Corrected entry: When Mikayla is tied up by the Tarantula People, the rope is only around her upper arms with the knot in front. Since her hands were free to move around as we saw when she was talking, a warrior as skilled as her should have been able to untie herself and escape.
The One About Mikayla's Friends - S2-E12
Corrected entry: Mikayla and Candace are wearing high heeled sandals when they talk to the kings, are both wearing flats when walking in the jungle and then both are in the heels again when they are trapped in the volcano.
Correction: The girls are still wearing the sandal flats when in the volcano, they probably just changed into them to walk through the jungle.
Correction: So she decided to play it safe and stay put; you can't categorize your assumptions about what a character should have done as a mistake.
