You and Grime (y'all can include Sasha if you want) were planning to sabotage yours, Sasha's, Anne's and Marcy's return to the earth by snatching the music box and dictate over Newtopia. When the plan worked, Anne was mad.

Marcy: “Calm down, Anne. We can peacefully-” Anne cuts her off and starts yelling at you sitting on the throne.

Anne: “No! I am done helping you, I'm done trusting you! You're a horrible person and I'm done being your friend!” She said as she looked at you with rage in her eyes.
