Yeah this arc has been going on for quite a long time, but Basically Its winding down to The russians are helping escort them out, roberta is still trying to kill the americans, the young master and fabiola were about to head back to venezuela until the young master decides to stay and help roberta with whatever she is trying to accomplish, and then to head back to their home together.
This one is going to be a pretty long arc when put in anime form, unless they wash it down. But I guess its overall a decent arc, just kind of drawn out a bit long. Guess its needed for character development.
