For Klaus, this was amazing, a situation worthy of admiration. The thing is that he was learning all this under an intense wave of complicated, tenacious, and stinging attacks.
Very powerful and hard to avoid. He was having great trouble facing Jasmine; she was too powerful.
Still, thanks to her and her peculiar teaching method, he began to understand more of his power and ability.
He was able to begin to delve deeper through the energy.
She was not teaching him only that. The main purpose of the training was for him to understand how to use the energy for his own benefit.
So she started explaining to him how he should use it and what he should do with simple explanations. It was the first time she felt so good teaching something, and she didn't know if it was because Klaus was teaching her or because she was enjoying the moment of hitting him, but the reality was that the training flowed calmly and smoothly.
