Fellow Alchemists, I'm hoping someone can guide me to particular brief scene that was in the last 6-8 episodes.I'm…
The full moon scene is in the starting of episode 2 when Jang Uk pulls Mu Deok into the hide out. We see the full moon and then the blue soul shifter marks in Mu Deok's eyes. There's another brief scene where the camera pan to the sky and we see the moon behind the clouds - that's in episode 15 when Master Lee is talking about a person being born with the King's star and the energy of the 7 stars.
The scene you're referring to with Danggu is not actually a full moon. It actually a fire cracker that Jin Mu's minions use as a signal to stop fighting and run. The only other time we see that fire cracker being used is by Mu Deok in episode 2 to signal to Jin Mu that she's alive.
JSM portrays cold heart Naksu, smart and busy Mudeok, and elegant Buyeon really well. She is a great actress.
Bu Yeon is the biggest mystery in AoS! Characters keep mentioning that Bu Yeon was really kind and nice but in the 10 years she's been lost, it looks like because of the ice stone and as she has gotten older, she's become more authoritive. She seems to be the only one that realizes what the ice stone means, the full extent of it's powers, and what it would mean to have such power. She's kind and people probably think that she's gullible (like So I) but in actuality Bu Yeon is pretty smart and wouldn't let people walk all over her. The change in tone and attitude we see from Bu Yeon inside of the ice stone while she's talking to Naksu is probably because Naksu was being ignorant.
