Kim was right in that Jimmy is always "down" and in trouble, and she is always there to help him.

But Jimmy is also right about their power dynamic. She'll be there to to "save" him, but she doesn't view him as an equal. She'll "get down in the dirt" with him when it helps her goals. But as we saw, as soon as she saw that he still wanted to open a law office with her, she immediately ran to offer herself to a high powered firm.

I'm expecting/hoping that the finale puts an end to that dynamic. Not that she'll leave Mesa Verde to join him, but that they become equals as scam artists/lawyers.
