[] Broad disclosure. Give her a filtered version of the events as you know them. You had a Vision a while ago, saying aliens were coming and that they were hostile. Tell her everything through the lens of human ki users being the active parties.
The framework of this one is, in fact, the truth. We did have a vision of the invasion and the scouts. There is a hidden society of ki users on this planet. They do actively work to hide themselves from both the greater galaxy, and the rest of the planet. And in many ways, they are human; their blood is not purely Saiyan, and it's impossible that some aspects of human society, both from Earth and from Garenhuld, haven't filtered in to some degree.
But for now, we maintain the Masquerade.
Unless and until the Exile society on Garenhuld can achieve the following results, I personally will continue to vote in favor of maintain the Masquerade:
1.) Maintain the freedom of government, will, etc. of the people of Garenhuld; my interpretation of population figures, and @PoptartProdigycan correct me if I'm wrong, is that Saiyans are still a non-majority of the planet's people, but a very large margin. If breaking the Masquerade would result in the Saiyans essentially ruling over the Humans, solely due to power levels and ki use, that's a net negative I personally am unwilling to accept. The Garenhulders may be "boring" to us Questers, but as far as I'm concerned they have an inherent right to live their peaceful, "boring" lives without us becoming violent overlords.
2.) Maintain the secrecy of the Saiyan people from the broader galaxy; all indications seem to be that if the galaxy knew Saiyans existed in number, they would freak out and either try to "recruit" us as "protectors" (read: fight their battles for them), or try to kill us all as obstacles to their own plans for glory and conquest. This point is in particular focused on the basic fact and knowledge of Saiyans existing at all. I don't want this revelation happening until we're in a position to handle the potential fallout, no matter the scope.
3.) Maintain our "silent running" vis-a-vis Ki use in relation to the broader galaxy; by this I mean we continue to do everything we can to not broadcast our power levels so strongly it's assured that we'll be felt from several systems to several parsecs, to even a whole galaxy away. This is for the sake of all residents of the planet, and relates to the general danger of the broader galaxy being able to go "WTF IS THAT".
4.) Maintain our (hopeful) security and secrecy against The Enemy; I feel like this is pretty self-explanatory.
5.) Find a way to disguise power levels higher than FPSSJ+Golden Oozaru; because if we can start hiding SSJ2, SSJ3, etc., then we're playing a whole different ball game. This largely connects back to 3 and 4, but is its own thing too.
-- but I'll leave it open for a bit given that I'm working on something else right now anyway.
