The scene toward the end when Vince goes to Owens apartment and asks how he's been...like he hasn't seen him in months. They work at the same place right? I don't thunk Owens character quit his job? Or maybe he did?
I just figured he took a leave of absence or decided to handle cases privately for a while. In fact I never really bought that they conducted every case jointly in the first place.
I've had a lot of sobering thoughts in my time Del Boy, it's them that started me drinking!
Yes they worked together as Divorce mediators, Im not sure if it was THEIR company or not, but John might have decided to take on his own cases with out Jeremy for awhile.
