What are your opinions on how Moon reacted in the Rigel episode?
well, everything Moon did in Regal's dimension was pretty good, giving "permission" for Carme to run, trying to calm him down before focusing on the portal device at Carme's insistence, and it made sense to try to quiet him because Moon had no idea how hostile Regal might be, or how insistent on finding them they might be.
Once they got to the house Carme made it very clear he didn't want to be touched, didn't want Sun to talk to him, and wanted to return to the Moon haven alone. Moon respected all of this. The "That's all I needed" line was clearly more about the fact that Carme hadn't verbally or non-verbally confirmed he was actually understanding what Moon was saying, hence him asking for confirmation he got home safe but accepting the "shut up" as a valid acknowledgement. Additionally, Carme made it clear, multiple times, that he wanted to be alone/for Moon to leave so, obviously, once Moon was assured Carme was cognizant enough he left, trusting Carme would be able to get to Moon haven fine, because again, Carme didn't want Moon to come with him.
So overall everything Moon reacted was as good as it could be and still be in character!
