  In this week's episode, everyone but Alex will notice a spark that's developing between him and intern Morgan (Amanda Fuller). "Karev's really oblivious to the fact that everyone's rumoring around the hospital that they're doing it," Fuller tells us. "They're spending so much time together, and they bicker and banter like two kindergarten kids who have a crush on each other, so he begins to realize that everyone may be right about her being into him."
  Sorry, Kasey, but I think it's a safe bet that the duo's early scenes will traffic highly in sexual tension. "Semi-platonic relationships are the fodder of great television," executive producer Carol Mendelsohn says. However, I don't think the duo will ever go much further than flirting. After all, D.B.'s married and Finn's not so great at relationships. "She has been married a number of times and has a real thing for cops," Mendelsohn says. "So she's in the right profession."
  How about his ex? Elizabeth Reaser's Tammy conveniently returns to town to cover a major sporting event. Once she learns that things have soured between Will and Alicia, what's to stop her from pouncing? Nothing except that Will may already be getting all the support he needs from an unlikely source. "At strange times like this, Kalinda, as cold as she can be, has a certain warmth and affection toward Will that starts popping up again," executive producer Robert King teases.
  When Leslie puts her foot in her mouth and calls Bobby Newport's dad Nick a jerk — just moments after he dies -- the election will take a turn for the ugly. Look for Donna to save the day by sacrificing the thing she loves the most. Prepare to grab some tissues!
  The show is definitely keen on revisiting that story line, but it's all about timing. "We're having talks about whether we're bringing him back by the end of this season," executive producer Andrew W. Marlowe says. "But we're still waiting to hear on Season 5. If we get the Season 5 pickup, it's something that we might wait and make more of a meal of next year."
  The tension among Shane, Rick and Lori won't let up, executive producer Glen Mazzara tells us. "Shane has designs on taking leadership of the group," he says. "The Rick-Shane tension will play out and everybody will be put in the middle, including Andrea. That ripples out from just a Rick-Shane-Lori story."
  If you think couples therapy is viable, then yes! "They both feel the relationship needs resolution, so Violet suggests that they go into therapy. Pete is reticent about the idea because he feels overanalyzed by Violet anyway," Tim Daly tells us. "He's not yet decided whether or not he can do it, but he hasn't said no."
  Not really. "Brennan is pregnant, so we'll just leave that as is," Geoff Stults says with a laugh. Although Hodgins will mention his pals back at the Jeffersonian, Stults says the real fun will be seeing Hodgins, who comes to Walter in search of aliens, in full-on UFO geek mode. "There are two different types of paranoia: Hodgins believes in the extraterrestrial; Walter believes in the conspiracy. And they both think the other one's crazy," Stults says.
  "I think you might be very happy by the end of the season," Jennifer Johnson promises. Until then, let Parminder Nagra catch an on-set nap or two.
  Very. The episode features a brother and sister who suffer from delusions passed on to them by their mother. For big brother James (Kyle Gallner), the mother haunts his dreams, telling her son to murder women she calls "the devil's wives." So he does, while lil' sis Lara (Madeline Martin), who carries a physical reminder of mommie dearest's wrath, tags along.
  : Jane is switching teams. Get your mind out of the gutter. She's ditching her friends to play for a more successful kickball team. Who can blame her though? Dave is really pretty awful out there.
  Nikita may soon confront her deadliest foe yet. The show is currently casting for a depraved psychopath who Nikita captured five years ago when he attempted to sell nuclear weapons to a terrorist group. But he'll soon be back on the hunt when Percy offers him a get-out-of-jail free card in exchange for the nukes.
