Now, assuming that enormous chain of guesses and assumptions was right, Mori Biwako had taken advantage of one family member's invitation to bring in another. The kid—no, it was worth making a note of her name now—Mori Ami was an effective counter to that woman's efforts to restore the numbers advantage, and with the former Mizukage candidate and a third faction's representative on board, the Mori clan head must have been preparing a serious blow against the Mizukage. Jiraiya imagined she'd force her to commit to something big in front of him, something which would strengthen the Mori's position and advance their own agenda in the negotiations.
All within the context of a pleasant family dinner, of course, without any of those other pesky diplomats to get in the way.
Then her darling grandsomething had swept the carpet from under her. In a context where the Mizukage was being reminded of her vulnerability before her backers (which Jiraiya assumed the Mori to be), Mori Ami was offering the woman the support she needed, on the condition that she follow Ami's foreign policy. At the same time, she was essentially holding the threat of alliance with the Hokage over everybody's head, saying that if they weren't going to steer the negotiations the way she wanted, she'd back the Hokage who would. Jiraiya almost wanted the Mizukage and Mori Biwako to turn her down just so he could see what her game plan was for supporting the sovereign leader of another state against her own. He doubted she was going to go the Keiko route.
