Lua, bored out of his mind, was training in his backyard. He held a sword akin to the one Sol was used to, and with said sword, he swung around while being instructed by her.
'Your form is garbage.' Sol said, not pulling any of her punches. 'I know you're still not used to your right arm, but at this rate, being single-handed will be better for you.'
"Thanks a lot." Lua decided to speak out loud in response, as he found thinking about it to be weird. Of course he was being satirical in this response, but that didn't mean he wasn't taking her advice to heart.
This was their second training session since he had built his new arm, and his main goal was not to become an expert in using the sword, but to become familiar with the arm. Of course, if he would be able to learn sword-play, it would be much better.
