What was the secret that Calleigh found out about Eric in Season 7: Episode 3 of CSI:Miami?

Two murders are committed at the home of Eric's psychiatrist, and eventually he and Calleigh determine that they have to violate patient confidentiality and read all the patient files, to see if there are any clues to who might have committed the murders. Calleigh finds Eric's file and learns that he is thinking of settling down and starting a family, and that he told his psychiatrist it would be nice if he could settle down with Calleigh. She doesn't let on that she read his file but it seems like she might feel the same way.
