I've been wondering that as well especially as it seems (that if they are going along the general idea of the the outcome (show ends with crowning and all the knights sitting down at the round table (sort of how I think with Smallville ends with Clark donning tights and cape)) then you have 3 of the main cast who are normally noble/gentry being of the lower classes, Arthur will be having to make some rather sweeping changes to not only law but tradition that may make him rather unwelcome among his people as even some of the lower classes won't like the change to the status quo. Unless they go the route that whilst Lancelot is out being all gallant someone makes him a knight (presuming it wasn't stripped with his banishment), Gwaine comes back and mentions that 'Oh my da was Sir blah of blah' and Leodegraunce turns up and spots his misplaced daughter and reclaims him just in time for them to get married. Hope they don't really go that route as its a little to soap opera for the show.

My main problem is that thanks to uni all I think of when I hear Gwaine is the story of him and the Green Knight which I had to read the Tolkien version and as my b/f kept calling him Strider in the episode didn't really help much to start thinking of him as a very campy version of Aragorn ( I did spend part of my time reading Sir Gwaine and the Green Knight picking out aspects if it that turned up in the books). Also my b/f and I had thought that as he got stabbed in the bar that the bad guy was gonna take his form (after he'd announced his lineage) and frame him seeing as it was nearly finished and it looked like no resolution that it was gonna be a 2 parter that it would turn into a random evil doppelganger episode (especially as they haven't done that trope yet).

It does seem a bit odd that they bring in the characters and don't use them unless they are t he bad guys seems a little too gimmicky at times.
