--Arthur can drive a car even though he's a knight of Camelot and does not have "we are both" memories. This sort of stuff drives me nuts because I cannot suspend my disbelief when the show is being totally illogical.
--The poison of Agrabah vipers doesn't make you poof up in smoke. Go ask King Leopold.
--"We've been violated!" Emma took Happy's axe because the writers can't get past the JMo/Michael Coleman Twitter nonsense.
--Lancelot did not hold the Siege Perilous in Arthurian mythology. It's actually kind of important that he never held it, ie: never found the Grail.
--Regina looked amazing in that red dress, but her "Evil Queen" conversation with Zelena was horrible. Make up your mind, writers. Is she redeemed or not because basically threatening your sister's life = Not redeemed.
--Hook admitting that he was the villain in the Rumple scenario of long ago. First off, FINALLY. Yes you were a villain and you did a terrible thing. But last week Hook was still calling Rumple the bloody crocodile and Hook hasn’t actually done anything to prove he’s sorry for what he did to Rumple (or to those that he hurt after Rumple). It’s one thing to say it out loud, but it’s another to make amends. We’re missing the other half of the puzzle.
-- Once again some terrible morals, or at least twisted ones. Guinevere and Lancelot chose to have an affair. Arthur did not force them to have sex. OUAT has a weird habit of taking away people’s ability to chose and making it someone else’s problem.
