Joseph and his brothers saw their father gesturing for them to come, which made them truly excited. Their father had finally returned and their wish to show him what they could do had finally arrived. Without any signal, the three brothers charged forth.
The three seem faster and more coordinated, compared to when they fought Alex. It was because ever since their little sister started training again they were able to figure out that they too were lacking. So the three started to retrain themselves, and this was the result.
Dan seeing the incoming attacks from all sides, smiled. He evaded the attacks with ease, he then noticed the style of fighting that was used by the three, was the same one he taught Alex, though incomplete it was still the same.
