If you stopped watching because of that, I have some bad news for you.

No he wasn't the Big Bad of 5a. Spoiler, no spoiler: It becomes Hook in some convoulted way. Arthur has no master plan and only sits around and gets captured for lying and nothing else and that's the last we see of him.

He wasn't killed off, the entire Camelot crew were forgotten, but are to be eventually addressed next season, we assume. So, Gwen is still "fixed" because noone will bother to free her.
