I agree with you. You just said a mouthful.

I don’t think she changed her sexual orientation. I think she is in love with or has immense respect for Bohannon and is sleeping with Campbell to distract him, giving Bohannon an opportunity to straighten things out for the RR. Just look at her facial expressions when he is behind her.
I have to agree with you about Ezra. I think the writers missed a great chance to do even more with Bohannon’s character. I was hoping he would be more of a father to the boy and the boy would grow to be like Bohannon. And then, one day, when Bohannon and the Sweed meet again, to the Sweed’s surprise, it is not Bohannon that kills him, it is the son of the people he killed. The boy will never get any revenge for what happened to him. This show is built so strongly on the good guy winning and good guy getting revenge. They totally missed it with Ezra. And worse, Bohannon never learned what happened to the boy’s parents so that he would have even more reason to kill the Swede one day. They are too quick to kill someone off for the instant dramatic affect. The show can’t live on new characters and killing them off alone.
