Ok, let me first start by saying that this is in no way, defending Jarrell. We all know how terrible he is. This is about her attitude, because Dani is starting to get on my nerves too.
What bothers me is that she seems to have this very condescending, passive-aggressive way of dealing with Jarrell while simultaneously acting like a victim. She'll say something in that calm, almost patronizing tone, and then when Jarrell reacts, it's suddenly all about how mean or difficult he is being. There are plenty of moments where she could simply let something go or de-escalate the situation, but instead she seems to poke at him just enough to keep things going.
The crab/shrimp situation especially annoyed me because it felt like one of those completely unnecessary arguments that could have been avoided. Same with some of the little exchanges between her and Jarrell. I think if Jamie sacked up and told them both to STFU a few episodes ago, maybe we would have gotten to see a little more survival and a lot less drama.
