Marvel's Iron Fist Season 2: What Does The Ending Really Mean?
8. Is Davos Gone For Good?
As said above, for all the build-up he receives the threat of Davos is dealt with in the first 20 minutes of the final episode of the season. Once he's carted off in ambulance, presumably going straight to jail afterwards, we never see him again. However, he does leave Danny with a cliched "you haven't seen the last of me, mwahahaha" supervillain speech.
This obviously leaves the door open for him to come back in season 3, and considering his status as Iron Fist's number one nemesis in the comics we wouldn't rule this out... But is there really any storytelling purpose to his return? Davos only has the one goal - to get the Fist - so it would be difficult to do this in a fresh way next year.
That said, he still hasn't properly become the Steel Serpent of the source material as yet, and we still don't really know how he connects with Madame Gao's Steel Serpent heroin from Daredevil season 2, so who knows?
