Following Sky, the rest of the beasts also reached them within no time.
The people that are following Jack are actually not that powerful. If Jack wanted to, he could have easily killed them. Even the beasts know that and they felt that even the people following him know that.
But they are still arrogant enough to go against him and chase after him as if he is the one at disadvantage. Sam didn't understand why Jack is tolerating him.
The people chasing didn't worry too much though. They just kept on coming, only after the beasts came in and scared the crap out of their beasts did the chasers understand they might have attracted the wrong crowd of beasts.
So, they turned their tail and ran.
Jack followed Sky and the other beasts as they came to Sam, who is standing there. Jack got off the hoverboard and slowly came to Sam.
"Its really you, isn't it? After a long time. It's really you."
