Mickey was upset with Donie. His little brother never wanted him in his lab because he would only mess things up. It wasnt fair! Mickey could easily handle things on his own. His brother jst didnt realize it!
'Fine, Donie, if you want me gone so badly Ill leave. I dont need you!', Mickey shouted to his younger brother and stormed off out of the liar.
'What are you going on about now?' Donie asks as he walks out of the lab but his brother was already gone.
