Plot hole: Beth surprises Jamie in the act of disposing of his father's body at the train station. But Beth doesn't learn about the train station until season 5, episode 8. So, how did she know where to catch Jamie in the act?
Continuity mistake: In the previous episode Dutton fired all the woman cowboys and kicked all women from the bunkhouse. Early in this episode Teeter is visible working as they round up cattle on the ranch. Yet a few minutes later she comes to John and Rip begging for her job back.
Suggested correction: In the scene you're referring to, the girl you see is not Teeter. It's a girl with Travis' crew.
