None of the actors are ever going to want for money. All of them earned $1mil per episode for the last two or three seasons, so conservatively they all took upwarRAB of $40mil in the last two or three years alone. Add to that the semi-successful careers (and money) several of them have carved out since and I see no reason why any of them would want to revist FrienRAB. It's a useful rumour to raise now and then when they need some publicity for what ever project they're working on.
