they building up this ghost and tommy thing 2 much, these dudes chatting on the phone like the good ole days and shyt. I don't think they will directly kill one or another if one of them does die.
I can see tommy and tariq setting up ghost like ghost and tommy setup kaanan in the warehouse where tommy bailed, but instead of tariq shooting ghost (while being held by tommy), tariq will think back to al the decisions in life he's made and how all of this is his fault. He tells "uncle" tommy and ghost he's sorry for all he's caused and he turns the gun on himself and fires... *cuts to end of the season*
we get a 5 year timeskip and ghost is driving around in his car with tasha and babygirl in the back seat. They stop at a light and tasha tells "James" she's sorry for not letting him live his dream and getting out the game, but james just spaces out and they arrive at the hospital to see tariq in his rehab. His self suicide missed by half an inch as he's learning how to walk again. Joined in the room is tommy, lala, cash and their 3 year old daughter Holly as the 2 couples exchange pleasantries and tommy speaks to ghost in private about a new opportunity in which ghost smirks and *roll credits*
