Luke and Chris were wayyyy too nice to her. They should have kicked her from their camp the first time she threw away a tool. Either get it back and apologize or you're out. One strike and you're out. Survival is no joke and they can't afford to put up with her crap.
Also, why wasn't that turtle killed and eaten? Sean is a character but given his background I'm not surprised . His 2 partners, Danielle and the red head (with the perpetual smirk what's her name) really irritate me with their negative attitude when he's actually doing something productive. Alll they do is roll their eyes at him. Turtle selfie? C'mon! I would still kill and eat it no matter what they said. More food for me and I guarantee in a few days they would be eating it too.
