[X] Full disclosure to mum about the Scavangers circumstances.
- [X] Explain that they are a bit like Utau, though they suffered under a much worse group than Easter.
-- [X] Mention that Manticore are part of the government, unlike Easter, but like JPs, and so they don't trust any officials.
--- [X] And unlike JPs, they are evil. Like Easter.
- [X] If possible, avoid telling her that Kana is a murderer. That doesn't seem like it would go down well.
[X] The most important part of the truth: they don't trust anyone but you and each other. And they're not that sure about you.
-[X] The danger is that they especially don't trust people like JPs, and the entire country knows you've been talking to JPs. They don't know for sure that you didn't tell JPs anything about them.
[X] Plan Keep the Secret
-[X] Tell your mother that it's a secret you promised to keep and so you shouldn't just give it away just because you haven't heard from your friend for a rather long time. How ever you are worried for your friend and so you are going to check up on her even if she won't agree or won't give permission, Friends are more important then that after all.
--[X] Calm yourself a bit, and bring up that there doesn't have to be that much risk. That they had some bad experience with strangers and are now very wary about them, but they are fine with people they know well enough.
---[X] Suggest that you can use your psychic power to get a good look from outside though, so it's not like you even there is any real risk. And if mom wanted to help you with a light disguise so journalists there isn't really much to worry about at all. You could also keep her on the phone if that would make things easier for her.
----[X] If any further good ideas come up that don't break the promise, you can consider those as well of course. But you can't possibly not check on your friend if she might be in trouble.
[X] Truth Will Out -[X] You suspect there's either one of two reasons why Kana is no longer returning your calls. Either something bad has happened to them, or else they saw you on the news with the government agents and got worried that you betrayed them. If it's the first case, you ought to tell your mother everything - they'll need all the help they can get; they surely won't hold it against you if you did it to help them. If it's the second, you need to prove you haven't betrayed them. -[X] The only way to let your mother know the truth without betraying your promise is if you take her to the Scavengers and let them tell her themselves, which will also prove to them you didn't even tell your parents anything. But if something bad happened to them, it might not be safe to take her to their house. -[X] You don't know which one is the case, but you DO know 2 people who might potentially be able to foresee whether it would be safe to bring your mother along. One is your school principal, Tsukasa Amakawa. The other is the fortune-teller, Saeki Nobuko. You don't know whether you'll be able to reach Tsukasa, but your mother is professionally acquainted with Saeki and probably has her phone number. If not, you know exactly which TV station she works at and can call there. -[X] You know your mother has a certain regard for Saeki, perhaps not enough that Saeki could convince her to leave everything to you, but enough that if she predicted it would be safe, Midori could be convinced come with you and hold onto her questions until she can speak to the Scavengers for answers. -[X] Call in help: --[X] Saeki Nobuko. Without telling her anything about the Scavengers, request a reading on whether Midori would be safe if she were to come along with Amu to the house they plan on visiting shortly. ---[X] If the answer is positive: ----[X] Bring Midori Hinamori along with you on your trip, explaining that she should hear the answer from the horse's mouth instead of Amu. ----[X] Bring Miki to scout ahead, just in case her prediction was wrong - even Tsukasa wasn't able to see the demons coming, after all. ---[X] If the answer is negative, or if Saeki is unable to give you a clear answer: ----[X] The Scavengers are likely in trouble. Tell your mother everything.
