Boris Kalashnikov, often referred to as B, was a member of The Grove Street Collective and an OG member of the gang.
Boris' main contribution to Grove Street is his knowledge and outside connections. He often does work outside from the gang on his own instead of running with the usual gang members to make new deals and bring in allies.
In July, Boris handed in his keys and left The Grove Street Family. It is not known why he did, but he still owes the gang 80k.
