Kaz:...I know it's not. I just like teasing you.
Kaz: Yeah but he could've walked away! It would have been hard with you being in the state you were in, but he didn't have to fight you. Plus, I think he's a hypocrite. I mean, don't get me wrong you're not in the right either-but he's just as ambitious as you are, probably more. And he's clearly willing to do bad things to make it to the top. In the end...you're both pretty much the same.
