Contessa speaks up for the first time, in perfect accentless Quenya: "What is the precise goal you wish to achieve? For the government to trust you, or for São Paulo to be put back and lived in?"

"- more the second thing. I guess you can't do things like 'for everyone in Brazil to be safe and happy'."

"Too many powers interfering," she shakes her head. "I'd get a result, but it wouldn't be guaranteed to work. I'm most reliable for short-term plans I can directly act upon to solve and long-term large-scale ones where individual actions get smoothed out."

Nodnod. "Then I want them to let Sao Paulo be inhabited and be on reasonably friendly terms with me so I can do other humanitarian stuff there uncomplicatedly."

"Then what you will do is practice swapping bodies with a basement-dweller you, using your invisibility and illusions, until you can do it perfectly so not even a camera can notice it. They currently suspect you are some form of Master who has a projection power; you'll lie about it and say that when you create basement-dweller versions of people you can have them swap bodies, and you will use your teleportation to trick them into believing you should they question you. Be honest about your motives, and continue interacting normally. I'm hitting a dark spot at this point but it should have cleared up by the time you're reasonably sure they mostly believe you. I'll give you coordinates to teleport notes to, you can write them in ultraviolet and we will be able to communicate that way."

"Your power is cool. Will do."

She gives him the coordinates, and sends him a mental image via osanwë to help.

And he practices swapping with basement-dwellers of himself!

The others can continue discussing tactics while he does that, although Oliver's kinda distracted by the practice.

It's kind of fun to practice. After a while he has it.

Then he's good to go to Brazil.

"You'll be careful?" Legend asks.

"I'm an indestructible teleporter."

"Just say yes for my peace of mind," he says, smiling.

"Yes Legend I'll be careful," he says, flapping his wings, and he goes back to Brazil and lands invisibly beside his body.

His body is... not just as he left it. It could plausibly have been how he left it but he has an eidetic memory; he can tell.

...could just be to check whether he adopts the new posture or not, but also they could've had something done to it with powers. 

He writes Contessa.

Does your power teach you languages or did you do that yourself? Also why's my body funny.

My power teaches me languages, and they moved your body to try to wake you, and then tried harder. Nothing's currently wrong with it, though.

How does it do that? Like, do you just know any facts about the language you ask yourself?

And he swaps with his body and sends it away and 'wakes.'

I set 'communicate with this person in their language' as my goal, and the simplest path is doing it.

There is a knock on his door as soon as he stirs.

"Come in."

Doctor Ximenes walks in, looking very stern. "We should talk."

Nod.

"I know you left."

"Yeah. I went out adventuring and then there was another attack and I wanted to help."

"How did you go out, and why?"
