The Rooms of Antiquities, the pleasant female voice can be heard from the earbuds of the electronic tour guide, contain a number of peculiar objects, many of which are not, in fact, ancient. Several of them were in fact thought to be ancient until they were discovered to be forgeries, or merely more modern pieces confused for older ones.
"... Oh. Right." he says, looking a little bit sheepish.
"Yeah, no, you're probably better suited to that card than me."
"Yes, it's even more important that you be careful with it, or it'll change you permanently."
So Theo sits down, facing the grass, summoning and re-summoning Change to do things. He wants to see his current limits with this card.
He might be at it for a while. He seems to be somewhat inspired. Maybe he likes this card.
For now, he can only change one thing at a time. He can change physical characteristics and switch things up, and unlike the other two cards there's a definitely feeling of potential there. It's less one-note than the other cards, more versatile, more potentially powerful... and deadlier, if left unchecked.
He's honestly having so much fun, despite the current limitations. He's going to be at it for a long while unless interrupted, and while the "deadly" part is potentially concerning... He's still here, changing and unchanging so many things. Eee.
Who'd've guessed he'd enjoy it so much?
"It's so much fun! Why did you let me have it when you could be doing this?"
Heeeeee. So much fun!
"I kiiiiinda already did that. I don't find it that much fun. And you're still adorable."
"Oh my god I could do this for days!"
Even being called adorable won't dampen his mood. He doesn't care if he seems macho. Alteration! Fun! Wheee!
... Eventually, he realises that his last sentence came out in a bit of a squeal.
Cough. "Uh, I mean, this is really fun."
And then: back to alteration! Whee!
"Oh my god your fragile masculinity can't even withstand having fun with magic. That's also kinda adorable."
