Throughout the SeriesEdit
In M.E. Time, Jake and Dr. Rossi meet whilst they are working on the same case. Jake believes that the cause of death is natural causes and begins to take lead but Rosa tells him to be a good seconds. Although Jake has agreed to take the back seat in the case, he ends up taking Dr. Rossi out to dinner to "follow up" on the case. They end up hooking up but Jake later tells Rosa and Amy that he can't tell if it is weird or sexy. They ask him what it means and Jake tells them that she has a corpse fetish. She got Jake to pretend to be a corpse and asked him questions about how he "died" which they both find gross. Later, Jake says he will go and get the autopsy report (so that he can continue with his natural causes theory) for Charles (who believes it was murder) but ends up having sex with her. Charles and Rosa come in and find Jake in a body locker and Dr. Rossi half dressed. Charles stands up to Jake and Jake agrees to be Dr. Rossi's assistant and help with the autopsy. They find evidence that it was murder and Dr Rossi propositions for him to stay for the "post mortem" and have sex again. However, Jake has been turned off by the autopsy and tells her that he's had enough with the strange sex.
Dr Rossi seems to be friendly and intelligent although her defining characteristic is her strange fetish for corpses which is eventually the reason that she and Jake break up.
Jake and Dr. Rossi briefly date although Jake finds her corpse fetish rather strange although he plays along with it. After being chastised by Charles, Jake helps her with an autopsy and they find evidence of murder. However, Jake breaks off their relationship as after the autopsy, he can no longer play along with he corpse fetish.

- Dr. Rossi has a corpse fetish which involves Jake pretending to be a corpse whilst she got him to answer a series of strange questions on how he "died".
- Her corpse fetish strongly suggests that Dr. Rossi may be a type of necrophile - a person with a disturbing sexual attraction to corpses.
