"Mhm."

"You're doing well with that exercise. Usually children have to build their reserves and control for a while. For you - next I would suggest learning the hand symbols, and the related chakra motions."

"Bring it on."

There are twelve standard hand-signs, that all require both hands. You can perform any technique without them, but these are rather like individual motions in a kata. The point is to train your muscle memory, so you don't have to learn the chakra motions for each technique from scratch. The hand signs also help individually - mapping the Ram's chakra motion onto the Tiger symbol would confuse enemies but also will result in a less efficient technique.

Explaining the actual chakra motions is complicated, and requires an extensive amount of Tobirama trailing his own chakra through Cam's to understand it with any speed.

Cam takes notes; fortunately he can do this without using his hands.

"Once you have those very thoroughly, I can teach you individual techniques that require them. Though perhaps the shadow clone should be first - that uses a modified Ram sign."

"If you can use clones to read, can you also use them to practice stuff?"

"Yes, exactly. Other than the cost issue, they're an amazing force multiplier." 

Wag wag. "And the cost issue isn't! All right, ram sign modified how?"

He demonstrates it, along with the chakra motion.

Cam will attempt this. After pausing a moment to become comfortable with the risk that his clone will be indestructible and there will just be two of him. Okay, now he's ready.

Nothing external happens initially. His buzzy feeling might do a weird split right at the end?

He will keep fussing with it for a minute before asking what he's doing wrong.

Tobirama will walk him through it again, a bit more slowly, pointing out specific mistakes.

How about now? Poof?

Poof!

"Weird," says the clone. "Okay, how do I make sure I can fold back in properly?"

"Clones can dismiss themselves by disrupting their chakra patterns. It's the same as breaking an illusion, just larger scale." He explains how to do that; it's basically 'chaos buzzing.'

Buzz goes the clone.

The clone dismisses, and Cam gets the newly formed memories.

"Wow that's freaky. Okay. Coooool."

"It's good this worked."

"Yeah, I'd been a little concerned that the clone might be as indestructible as I am and then there'd just be two of me forever, which wouldn't be the end of the world but wouldn't be something I'd seek out."

"We might want to test if the clones are indestructible at all. Ones I make, even like this, aren't."

"Yup, I plan to test that. I also want to know how deterministic I am!"

"As a warning, try to avoid making too many at once. I developed a mass version of this technique, that knocked me out from memory overload when I dismissed it. 'Too many' is, unfortunately, variable between people."
