(Stalin) This is my chance... to become the Chairman of the soviet Union, and they will never see it coming. But apparently, Trotsky is next in line; I have to get rid of him. Hm... I'm already the General Secretary... which means I can slowly dismiss Trotsky's followers, and replace them with my own!
(Zinoviev and Kamenev) Stalin! Will you help us prevent Trotsky from obtaining power after our dear friend Lenin?
Of course I will!!! We will never betray each other! BROTHERS!
(Stalin) I have given false information to Trotsky about Lenin's funeral... Now, I can spread rumours about Trotsky's loyalty and so on...
(Stalin) My brothers and I have parted ways... They united with Trotsky... but I already have too much power. I will find a way to defeat and exile them from MY COUNTRY!
WAIT, STALIN, WE ARE STILL BROTHER RIGHT??? PLEASE!
