My b it was actually 2. But the point being if you take Liara on the mission to fight Kai she makes a comment about the name of the hotel the mission takes place in. It is "Hotel Azure". She tells shep that azure is asari slang for pussy.
Was it not a mission for Kai? No it was an asari or something. Man it's been a long time since 2. Lmao still, that little tidbit always stuck with me. Especially coming from Liara
