I agree with most of you, except that missing at say 12-15 feet when shooting at a live target under time pressure (she couldn't slowly take aim) is certainly possible, even likely. Especially if she was dumb enough to shoot at his head instead of center mass.
On Carol, she's done it once before and saved the crew, but does anyone else sense a Willis Reed moment? Maybe in conjunction with Morgan? The two retired fighters turned pacifists finally join in later and turn the tide of battle. I can see it coming a mile away.
I'm glad we finally got to the point where everyone, except a few at the Kingdom who are coming next, know that they can't just Neville Chamberlain their way out of this mess. Evil must be fought, it's the way things are.
