I wouldn’t be at all surprised to have Axe back in the country and back in business legally in the last ep of the show.
As for Taylor and Wendy being stuck at the new company—both of them made more last year than half the workers in this country make in a lifetime. At this point, they’re working because they want to (unless they have some contract that they can't get out of without losing all their savings and investments). Wendy is a therapist or whatever; she can always go into private practice (and will have half of wall street banging down her door for appointments); Taylor is, if nothing else, a math genius and would probably have no trouble getting hired by a B school or university if they wanted to keep working. Both of them have options, so I am shedding nary a tear for either one.
