Eric and Calleigh 7x19 [the picture scene]

Ryan and Eric talk about the photos that they got from the paparazo that was in the tree and taking pictures of the team. Ryan and Eric see the picture with Calleigh and the horse trainer-Terrance. The next scene is when Calleigh is called down to the morgue by Eric. They meet in the body bay, he tells her that someone has been watching them (the team) then he shows her a picture of her and Terrance. Calleigh tells him that she will will call Terrance to make sure that he watches out, Eric is a little jealous that she has the mans number in her phone, but she quickly puts out that flame when she tells him that "this was before you and me" and "can we talk about this tonight?" So are they living together or are they just sleeping together at the others house? One thing is for sure, Calleigh is no virgin when it comes to men.... (And no, i don't mean that in a cruel way..its just that the writers are always writing Calleigh in different situations that put pictures in peoples mind that she has had sex with all the men that she is/has been with)
