BTW: I googled for Lewis and Clark - interesting part of American history. The things you learn at this board.
It's so interesting, isn't it? Sacajawea is considered such a hero that she appeared on a US Dollar coin a few years back. Sadly, Americans just won't embrace dollar coins over bills - so I don't even know if it is still being minted. She was only around sixteen and was either pregnant or carrying a baby on her back during the journey. She was so respected, she was allowed an official vote as a member of the corp. So was Clark's slave, York. They are considered the first woman and first African American man to have voted in an American election of any kind.
Anyway, I agree that the propping of Archer was a writing mistake. It's writing 101 - show the viewer/reader and let them decide. From various interviews and commentaries - I've gotten the impression that the writers were under pressure from UPN to make Archer "more heroic" early on - which flew in the face of the concept that he would learn to be heroic. I like the concept that he wasn't perfect and he was in over his head - but like others, I would have liked to see more consequences for his mistakes and more dependence on his people.
One of my favorite Archer episodes is Strategem. He's engaging in some clever spycraft, he's depending on the expertise of his crew, making a tough ethical decision or two and he's furthering his cause without bloodshed. There's almost no propping in that episode. I think if he had been like he was in that episode from the beginning, it would have served the show well.
