"It's on the other side of the apartment. Presumably in a window," he says to Sadde. Then he asks Kero: "If I give Sadde the key, can she use it to open the window?"

"No, only you can use the key."

...

"Can I have Fly then, Sadde?"

"Only if you let me watch."

He keeps smiling, though it might be a bit forced now. "Of course, darling," he says. "Now, can I have the card?"

"Here," she says, and grabs it from her bag. "You be good to him, okay?" she tells the card before handing him it.

It's not gonna bite him. It's just a card. He takes it and goes out of the building, trying to see which window corresponds to Sadde's apartment.

It's not hard to find, and it is indeed closed.

She follows him! That she wants to see.

Of course she does.

So he manifests Fly, somewhat desperately hoping it doesn't attach wings to the staff again.

Ha.

Okay. Well, he's already committed himself to this, and if anyone looks, they will hopefully believe they're seeing things. Except Sadde, of course. And Kero. Whatever.

He gets on the staff like it's a magical broomstick, and feels utterly ridiculous. But no, it would be worse to back out now. So. How does this thing go?

It's actually pretty smooth sailing. All he needs to do is think about where he wants to go, and oop, there he is.

(And thankfully for secrecy, they're in a somewhat secluded alley, not a whole lot of people will be able to spot them.)

(Well, that's good.)

He flies up to the window, hangs off it, changes the staff back into the key, and tries it. It almost seems too easy.

A strong wind starts pushing him away from the window when he tries the key, coalescing into a whirlwind.

Okay, well, he still has his bag, so he can just manoeuvre around slightly, make the key into a staff again, then awkwardly throw out Windy's card with his fingertips and summon her, can't he? "Windy, stop the wind!"

Wow, he still feels stupid, saying things like that. And it's really annoying, having to explain what he wants each time he summons a card.

It tries!

There's no more wind, however, because as soon as Theo stops trying to use the key, that wind coalesces into a floating winged lock, which proceeds to disappear inside the window's keyhole.

"Ugh!" he exclaims, then wills the staff to return to a key form, asks Windy to help support him if possible, and tries to unlock the window again.

It's a good thing he's got great upper arm strength, isn't it? Kinda weird, really.

That strong wind again and—

—Windy seems unable to do anything about it.

"The Lock is a special card! You can't use Windy on it!"

Sadde's watching this all from the ground and asks, "Couldn't you have told us this earlier?"

Theo grunts and tries even harder to fit the key into the lock. Even though there's no obvious place to put it, the Key seems to be okay with him trying that anyway, which is weird.

There might be a little blurring, but it's a bit hard to tell.

He does succeed—unlocking the window isn't the problem. The problem is dealing with wind strong enough to make him start to sway from where he's hanging.
