Yes. Rick Stetler is in the ep. He is actually the one who interviews Calleigh while a guest character plays the IA Agent who interviews Eric. One thing will be for sure, if there really is tension between E/C then the team dynamic will definately be interesting. I mean how could they could work together? Obviously he feels more of the animosity than she does. I think she feels more guilty than anything....but how can they work together? Unless one of them switches shifts? Things will be very "tense" otherwise. I did notice that neither of them are throwing the other under the bus. However, Stetler does ask Cal if she perceived Eric as "fleeing" the scene or simply, as he says, escorting Sharova. Cal hesitates...the spoilers change scenes before we get to see her answer....so I am wondering if her guiltly conscience will make her throw herself under the bus? Ya know in order to save him and allow him to get back to work? She does say to Horatio in an earlier scene that she doesn't know how to explain how she shot Eric while he was seemingly fleeing a scene w/o making one or BOTH of them look bad. H tells her to simply tell the truth.
