I just posted a photoset of Prentiss reacting to having to “snuggle” up to Karl Arnold to get information in Outfoxed. She seemed sickened by the entire encounter and said “getting intimate with a killer is so…different”.
There are those who would, in hindsight I think, look at this as proof of what is later revealed as her past with Ian Doyle. Like she was having bad memories, flashbacks or something. I look at it as proof that the “Emily is a super secret agent” storyline was trash.
