Uh huh. He definitely makes note of this.

He can go find housing for the night, since they checked out of the inn - this place is big enough there might be longer-term options available - or he can try and find Tetsuma, or wander around for a bit, or something.

Probably wander around for a bit until he runs into her.

He finds one of her clones, sitting on a bench off the main road and reading. She stands up when she sees him - she's got Tetsuma's face, though less distinctive hair and clothes - and walks over to him, saying "Hey Sadde! How's your day been?"

"It was fun! I'm in their astronomy dept."

"That's cool! So you're getting to work with plenty of math?" She starts walking, leading him towards the edge of town. 

"Yeah and it's so bizarre it makes no sense and I love it."

"It's great that you're having fun!" And similar light chatter about her day, the weather, and so on.

Eventually the road will take them out of the village, and along a dirt road across the heath, until they pass a medium-sized copse of trees. She veers off the road onto a small game trail, leading him into the center. Tetsuma drops down from the branches once they're out of sight of the road, smiling. 

"I found this great area for me to hide out in, and there's a path towards another village and the castle - you can stay here with me if you'd like, and from the perspective of the castle it'll look like you're housing in the village, or taking the long way to the town. How was your day?"

He retells the story!

"How about yours?"

"That's great! I didn't learn as much wandering around the market, I think in the future I'll just send my clones in when I want food or something and focus on jutsu development. I'm a lot closer to getting clones to merge with trees than I'd thought, which is great, and after that is getting them to travel through the root systems.

"I also meditated for a bit, tried to get a sense of the castle. They definitely have trees, and the space is definitely distorted, but I haven't yet managed anything more than that - I think my wood-sense also isn't going to trip any alarms, too, it wasn't interacting with the magic at all. Makes sense, since it's almost entirely passive, I'm just sensing the chakra that plants are already putting off."

He nods. "People in town have no relevant info on the lord? Also maybe now we have some time I could try to see if I can mimic your bloodline, it'd be useful for both of us to have it."

"Not much that wasn't said yesterday. Most people only have an opinion on what directly affects them. So, like, I learned that some of the supervisors of the help are known for being mean, and a lot about people's opinions on taxes, and some about the education system, but that's about it. I haven't found someone who's old enough to remember when he moved in, though I can put more effort into that."

"And, yeah, we should definitely see if you can copy me entirely. ...For that matter, you might also be able to mimic my chakra capacity, or at least the physical side of it. That'd be useful, building up chakra capacity can easily take years, and my jutsu are mostly chakra-intensive."

"Awesome. You're sure we're not being watched, yeah?"

"As much as I can be! Someone might be scrying on us with a method I can't detect, though that's really unlikely."

"Alright, then."

And he switches his body to... well, girl Tetsuma. He knows a lot about what Tetsuma's body's like.

And she walks him through the basics of wood sense.

It's pretty similar to the meditation to sense your own chakra, though you have to be still and focused outward, since part of what you're sensing is the echoes of nature chakra. (Tetsuma can't directly sense nature chakra yet, but the wood-sense allows for cheating.) You tune your own chakra to the chakra around you, then interpret the perturbations. If it works, he should feel something, like a vibration just under the threshold of hearing.

...nope, nothing. But maybe he can try to copy the... "physical portion" of her chakra...?

He'll suddenly feel stronger, and a lot more energetic. Like, no wonder Tetsuma's constantly running about levels of energetic. 

"—oh wow so that's why you never stand still."

"You managed to copy my chakra capacity? That's great! Though it'll probably throw off your control, especially if you only copied the physical portion. And, yeah, being energetic is usually a sign of naturally high chakra capacity."

"Wow, wow, I wanna run, I wanna go swimming, I wanna—do things—do you feel like this all the time?"

"Pretty much if I haven't exhausted myself! It's why I was going so stir-crazy on the ship. Though I'm also used to it, I think it's just the initial rush you're feeling?"

"Yeah. Just. Wow." He runs around a bit, and bounces, and jumps—"Woooowwwwwww!"

If he pushes off with chakra, he'll leave a small crater in the ground. Tetsuma wasn't joking about the 'suddenly poor chakra control' part.

She giggles while watching him.

He'll bounce around for a bit and when it becomes clear this extra energy is not going away he'll just force himself to stand still.

"Okay, so, lemme see if I got the wood thing..." Pause. "I totally got the wood thing."
