Grey didn't plan on spending a long time with his grandparents, he was just curious and decided to see them. Now that he has seen them, he didn't have any intentions of staying further.
"I'd like to see how strong my grandson is." Grey's grandfather said as they spoke.
"Dad, he's not one of the people you train." Martha didn't like the fact that her father was trying to get Grey to fight.
"It's nothing serious, just a spar with someone on the same level, don't tell me you're not willing to do that." Grey's grandfather acted like he didn't hear Martha's words.
Grey looked at his mother and nodded, "Sure, but I don't think any of them will make me sweat."
"Confident, I like that." Grey's grandfather smiled and took Grey with him. Grey's grandmother as well as his mother followed them as well.
