Season 2 of Iron Fist is now available on Netflix and I watched all episodes.
While it is a marked improvement over Season 1 and the Defenders mini series, the conclusion was rather confusing.
Specifically,
Colleen is shown stopping a crime while her katana glows white like her fist and Danny shoots two guns while his fists (and the bullets) glow yellow.
Which of these two is now the Iron Fist?
From what I had seen in the earlier episodes, the power of the dragon was transferred to Colleen, so Danny shouldn't have any special abilities anymore.
