Right now is the perfect time to bring Sean back even for a short stint. We have Dean back who is now a totally different character, we have Jean here for a short visit and she recently tried to kill herself, Stacey is on the verge of being released from prison and Roxy is happily in a relationship with someone who is really dodgy. DTC would be a fool to miss this perfect chance. I'm pretty sure Rob could be persuaded to return for a short stint after all the praise he gives to EE.
