[He remembers that part of the story, about the things Thrall had done for his people. He doesn't say anything but there's a small noise in the back of his throat as a sign he's listening and latched onto each word.

So…what he's getting out of this is that Jaina was brave and Jaina's father was kinda crazy but she didn't let that deter her and she risked losing her connection with her family in order to be honorable. It's a huge sacrifice. He can't even begin to imagine having to make that choice, and though he wants to ask why the other man wanted Thrall dead, he's fairly certain the answer is just "because."]

…well yeah. That's kind of a really big thing to forget. But how could he not see you two were working together? Shouldn't that have been obvious?
