Yesss… I know that was brought up years ago. I hope it’s been fixed.
Replacing the conjunction with a pause would have a similar effect. I quite like the line as is. It makes it sound like Lando is desperate to convince and nervousness has broken through the cool. But I wouldn’t rage quit the edit if it was smoothed out.
It’s not a big thing to leave it in, but to me it sounds like he’s trying to remember his lines instead of trying to cover up his nervousness.
