During the fight scene between Leslie and his men and Hidalgo, Jonah (Leslie's slave), appears defeating a conquistador and then when it's all over he's gone for the rest of the movie! He's a main character! where'd he go?! People don't just disappear!
Actually in the seen where bigwell says the worst is over and then is shot you do see him again as it shows a very short clip of him dropping to the ground for cover
