Sam, also did not go back to the Royal palace. He is also present in the VIP room alongside Oni king and queen, human king and queen. Naturally as their daughter and their sons were togethers, because of this, they also did not have to change the camera view present on the screen.
They could already see that Maria and the others already begin to advance in the forest and even though they were facing many powerful Monsters that they never faced before, they are still adapting in that tough situation while also collecting many points.
Fortunately until now they did not face any other teams and because of this, they did not have to challenge anyone. First of all facing another team is not a bad thing because it could also give them a chance to gain all the points that the other team had with them. But at the same time it is also risky because if they face a very powerful team then naturally they would be the one who loses all of their points.
