 The Union Depository heist is completed successfully , but Franklin is approached by two parties separately who demand that he kill Trevor or Michael . Haines and Norton contend that Trevor is a liability , and Weston wants retribution for Michael 's betrayal . Franklin has three choices : kill Michael , kill Trevor or kill neither and face their enemies together . Should Franklin kill either Michael or Trevor , he ceases contact with the survivor and returns to his old life . Should he kill neither , the trio withstand an onslaught from the FIB and Merryweather before going on to kill Haines , Stretch , Cheng and Weston . Michael and Trevor reconcile , and the three cease working together but remain friends .
