I just planned out the order of the storylines for the first half of October and the ones featuring those three characters will first pop up on the 2nd, the 5th and the 11th. So, keep a lookout for who might show up in the slideshow on those days. Though I can't say it will definitely be one of those characters because 1) it all depends if they have any "MUST" quotes left in their storylines and 2) more importantly, if, as in the case of Portia Fitzsimmons, she has any "MUST" quotes at all...
