Coldzera decided that to become #1 again he needs to be good in every aspect of the game, not only clutches and revenge fragging, but AWP, utility usage, IGL, mid-round calls, everything. Fallen doesn't like that Cold tries to take IGL role from him and being a godfather of Brazilian CS invites cold to his mansion.
"You were like a brother to me... but now you must go..."
Cold is mad, angry is overflowing him, he jumps on Fallen and strangle him...
Then it appears that MIBR actually was Fallen's org sinc he is the godfather of BR CS and 2faced Tolledo. No one knew this, but know they now, but it's too late, he is dead and due to financial problems teams disbands.
