That moment where you just give up and give Nestor Royce's branch of the family a hereditary position as knights of the Bloody Gate because they need to have a family seat to justify the political power you unwittingly gave them while also still letting Nestor treat the Moon Gate as a better seat to obtain so it makes sense why Littlefinger would bribe him with it.
