People, if you're seriously combing this meticulously for plot holes and other inconsistencies, stop watching the show now. Save your sanity. Stop watching Marvel Studios movies. Don't read any Marvel comics.
Marvel stories are thrilling stories, filled with heroics, peppered with comedy and drama (dramady!), chock-full of bad puns and swiss-cheese plots. The thing about Marvel is (on-screen and in comics), they give you enough great dialogue and pacing to make up for the terrible stories. And I say this as one of Marvel's biggest fans. I still read their comics and I love them. I love those terrible stories and the charismatic heroes and villains who star in them. It's good, cheap entertainment.
Like I always say, when I want fine literature, well I have shelves for that too.
Relax, stop fooling yourselves, and you'll be just fine. There's an old saying, "You can't scrub spots off a leopard." You can say "I don't have to accept these inconsistencies, I have a right to complain," until you're blue in the face, but you won't ever change good ol' Marvel. And thank goodness for that.
