From what I read more or less it appears that there was a luchese case at the time not sure which one, that there was a rat on and Big John assumed it was John, and with out any confirmation or anything they one by one started ice-ing him out have him the cold shoulder and were making remarks, to the point it became un mistakes le what they thought.

In the end it came out that he wasn't the rat is was someon else at that point the damage was done, there was no coming back from that.

They reached out when the found out they made a mistake I guess he made upnhi mind what he was going to do.

I know I dont have the story 100% not sure I missed some of it or he hasn't told all of it.
Serp, so it wasn't a one off isolated incendent the guys in the car, thre was multiple incidents prior too.
