I can only provide some simple summary from the documentary. And in the end, the story about the necklace/pendant is explained:
-Mai says in the very beginning that this is the very 1st time she's ever been to a WC in which Mao participates
- Mai arrived in Boston after the SP finished. She was worried about the results and checked right away after getting off the flight. She got to know Mao's in 9th place and had a mistake with the 3A. But since other elements are fine, it seemed that Mao only felt regret about the 3A but couldn't help it in any other way.
- Mai went to sub-rink to check Mao's condition of the practice, In the past, the sisters had the agreement that Mai would not go to any of Mao's competitions. But the agreement was broken since Mao asked Mai to go to Japan National last Dec.
- After Mai arrived, Mai actually stayed together with Mao and shared the room with Mao after SP. So before the FP they were together and relaxed a little bit. They were able to watch men's FS together.
- At the post-competition interview, both were very happy about the results. Mai said when Mao nailed the 3A and 3-3, she said: YES! And when it came to about 3mins of the performance, Mai started to cry. As a former skater, Mai was aware that up until then all the jumping passes were accomplished and she knew everything should be fine for Mao afterwards.
Finally, about the pendants:
according to Mai, both she and Mao received the pendants, from Mao's former Russian coach (Mai didn't name the coach), as gifts. They each got one with slightly different design (Mai got a silver one, and Mao golden), the purpose of the pendant is for protection and bless of good luck. Mao started to waring the pendant in practices since the beginning of the year, so she's quite used to have it now even in competitions.
