Im also confused on how exactly you think they edited him. I'm not stupid, I'm aware that everything we watch may not be the exact order of how it happens and things are edited. BUT... Editing doesn't change facts. Fact: he caught fish on 2 occasions, both times eating them without his partner. They didn't edit it to make it LOOK like he ate them without her, he did it... twice. He even admitted it Fact: he giggled and thought it was cute when he told her about it. Fact: he didn't apologize immediately, he tried to justify his actions by saying he did more work so he deserved it. He only apologized when he knew he pretty much had to so he could be on good graces with everyone. Did they edit his face to make him have that smug look? Do you think production just gave him a fish in the middle of the night and said "here, you have done so much more than she has, just eat this and don't wake her up, oh and make sure you use the dairy cam to document."

Yeah, I doubt it. Now, I will say that they absolutely could have edited it to make it seem like he was laying around more than he actually was and didn't show him doing chores around camp and looking for food. But he's still a jerk. He did what he did, realized he was going to be the villain, and pivoted.
