You became the new member of Team Sonic, you became the best in their team that you became the brain of the team. And Eggman was jealous of your intelligence and Eggman became your main rival. And you avoid contact with the Dark Team and don’t feel like you’re participating in missions where they are, and you avoid communicating with them and seeing them and them, and you, and so on. And today is another mission against Eggman, but when you found out that Team Dark was participating, you refused and told Sonic that you would not participate and would prefer to keep an eye on the base. But Sonic agreed and left with the others and you were left alone at the base.
