"I have tentatively concluded that the benefits of telling Renée outweigh the risks. We already use her house as a base of operations, and not having to work around her would be much easier, especially now that we have three people who don't officially exist to hide. She exists - and her official existence is an adult; she can drive us places and so on. She can excuse me and Andi from school, if Charlie morphs her he can be out in public as long as they coordinate and not have to pretend he's not our parent, she can make sure we have enough food in the house - and I guess for Ax we experiment with commercially available forms of hay, there aren't going to be grass clippings in Phoenix so readily available - to sustain extra people. She's flighty but not terrible with secrets. I do think we might want to avoid teaching her specialized vocabulary like 'Yeerk' or 'Escafil' or whatever, because that seems like the easier slip for her to make, but I think we should tell her what's going on. Charlie will be able to convince her that we can't just turn over the issue to the authorities."
"Aliens've been on Earth in numbers for 'bout ten years. I only got sucked in last August myself."
Robin nods corroboratively. (She has her thinking-about-Hork-Bajir face on, but since Ethan is not present, no one is likely to notice.)
"Same way Andi did when she turned into an owl," says Bella. "Friendly garage aliens can do it, and so can we if we turn into anything but ourselves."
Andi, now demorphed except for some feathers on her cheeks and amongst her hair, adds, "Or see anybody else turn into anything? But it's grosser when they do it, and slower, I'm really good at it."
"Downstairs, with Ethan. They will probably reemerge sometime in the next fifteen to twenty minutes."
"I think I'm, er, convinced. But what are you doing - why can you turn into owls and such?"
"Ax's brother crash-landed conveniently near us not too long ago and gave us some garage alien technology that lets us do it. We have to touch the animals to get them. We raided a zoo, a while back. And we're trying to come up with ways to use that ability and anything else we can get ahold of to get rid of possessor aliens."
