I tell them I will only deal with the boss and I won't join up until I meet him. If they won't accept that and we have to be enemies so be it. If the boss shows up I hit him with a counter proposal. Since his goons ain't shyt since I beat them repeatedly, I offer to become his right hand man at the top of the crew and help him rebuild from the bottom up to get rid of the weaknesses I've already found in his crew.
