Sadde snuggles up with her boyfriend.

"But there's the pretty strong possibility that it'll destroy or damage the place," she points out.

"… I mean, I'm sure Theo wouldn't object to leaving the room temporarily to go try it?" she says, smirking a bit.

Theo laughs. "Eh, yeah, probably should do. I mean, anyway, so far it hasn't actually been horribly dangerous things, just weird things like turning me pink? Might not want to be near anything valuable while I do it, though."

"Yeah, and there was the water. Also someone who's not the cardcaptor that is me should try it, too."

"Okay," he says. "You should probably drain your mana again in that case so we can actually test how long it takes you to recover from that? Or Juniper and I could just do it again until we get a result?"

"Yeah, I'm gonna go drain myself," she says, standing up.

Theo stands up likewise! Might as well go do the mana thing in a similar location.

So Sadde goes outside and starts charging papers, and then—

"—okay this is weird, I hadn't noticed this."

"What?"

"I'm not sure, I was going to charge this but I felt a—thing."

"A thing… before you charged it that, what, told you not to or what?"

"I don't know, it's just a thing, I have no idea what it is. It's really, er, slight? Tiny? Can barely feel it?" She tries to charge it anyway and—

—the room suddenly becomes really cold. She does charge it, but the room's cold.

"Okay that's– weird," he says, shivering a little.

She tries charging again and fails. And then snuggles up to him again because body heat and also boyfriend. "Okay, your turn. See if you can feel a thing, too, it's like... I don't know what it's like but it's really easy to miss if you're not paying attention."

He snuggles up too! "Should I try charging it and do it then or just, without doing anything?"

"...I mean I felt the thing just as I was about to charge that last paper."

"Right, yeah, but you didn't actually charge it so I was wondering– okay, yeah."

So he reaches for the paper and grabs a pen and intends to charge the paper and then moves to write the word 'water'.

No feeling, it charges alright.

"No feeling," he says. "Not that I could tell, at least." Shrug. "Might be because you drained your mana a bit before me?"

"Well, yeah, if the feeling's supposed to indicate mana drain then you presumably won't get it until your mana's been drained."

"No, I mean – I already drained my mana but I haven't had as long to recover it as you, I don't think, unless you've done magic since the feather thing? So your mana should have been higher than mine."

He tries it again anyway, seeing if he gets the feeling this time.

Not this time.

But he does the following. It's very similar to the feeling he gets around active Clow Cards, but not quite the same.

"Huh," he says. "That's– weird."

"Right? Maybe we felt it before but didn't notice it because we weren't paying attention or something, I dunno, but if we get warning..."

"Yeah, it'll be useful," he says. "Should stop us from stumbling over into the weird effects."
