Like she said. Beggars can't be choosers, and while she likes it when her paramours can take a hint and play the game of back-and-forth that she likes, navigating her whims and the dressings of romance, even as they lead here, she might as well get things into motion.
She already put her teeth around Oz once. It's not such a hard leap to understand that she would like to use them.
For that, he gets a single rose, fragrant and flushing from a princess pink at the edge of its petals to a lurid crimson at its heart; a key, golden and ornate and etched with the symbol of her kingdom, the open heart laid bare, billowing smoke and coiling with tube worms through its arteries; and a little note tied around it, penned so prettily in shiny blue ink, dotted with a signature and a heart, which reads, "Meet me at my castle. You do know why."
Well, one of them had to make things go a little bit faster, isn't it?
The things in question being... complex, to say the least.
Oz already mentioned to her how much he adored her, and yet he kept pushing himself back, saying things just to act in the complete opposite way.
One could say he was fumbling it.
The fact that he was scared of her just as much as he loved her didn't make things any easier, of course-- but it's not like he could blame her for trying to be a little more assertive.
Even with her odd methods.
Some might enjoy a gift such as this one, but Oz?
That... just makes him feel nervous.
A clear message. More than one, really - the key, the note, the actual heart given to him, all made it really hard to even breathe, let alone think.
It's the closest thing he got to a confession from the princess, after all.
Or a death threat, anyway.
When it came to Miranda, they were, more often than not, the same thing.
...well.
He might as well follow her instructions. Orders. Same thing.
The note is put in his pockets along with the key, and he makes his way to the Merkingdom's castle.
