Title: Emily Prentiss
Content:  Prentiss is shown to be an extremely competent, level-headed agent. She is not as affected by the nightmares that come with the job and manages to keep her cool in hostile confrontations. She is also shown to put herself in the line of fire, for example, volunteering to enter into the unsub's house to rescue his young son, and sacrifice herself for her teammates, as she does for Reid once in the season 4 episode, "Minimal Loss". She does not act rashly and there is only one rare occasion where she allows her personal feelings to interfere with investigations. It has been mentioned by Morgan that she has problems trusting others, preferring to handle things independently instead of asking for help, but it is revealed that this reluctance is due to her background as an undercover agent.
