Demetri was training with Mr LaRusso and they were doing muscle memory for demetri to learn karate. Demetri couldn't do it so he tells Daniel

"I really can't, I have no muscle" Demetri sighs as Mr LaRusso said

"That's what you lack, but you can do it" Mr LaRusso said to demetri as a person came up to Mr LaRusso and started to talk calling him dad

"Oh hey kiddo" Mr LaRusso hugged them as demetri tried to paint the fence again
