Sam: "Tell me, what was your relationship to Bethany?"
Kalagian: "Relationship? I hate the nineties. If you consider being tailed by a shortfused FBI investigator a relationship, you're a very lonely woman Miss Waters."

George: "Let me try scanning for viruses."
John: "You're supposed to be scanning killers, not viruses, George."
Bailey: "Why don't you give it some cold medicine."

(to the NOTW)
Bailey: "Interesting medium you work in."

Tony Abatemarco, the actor playing Allessandro deSalla, prominent artist, was also the NOTW in the third season episode "Where Or When". And Jennifer Griffin, playing the part of professor Desphande, also guest starred in the third season. The episode was "Perfect Helen" and she was the local police officer.
In the email Jack sends to Sam in the end of this episode, the picture of Sam and Chloe on the couch is actually taken from the "The House That Jack Built", the episode after this one.
Two of Bruce Gray's works of art (see Insight's trivia section) are used in this episode. During the scene where John and Nathan interrogate deSalla, you can catch a glimpse of Gray's "Wall Sculpture #16" work. When Sam and the woman from the art institute are ascending the stairs, you can see Gray's "Qube #3". If want to know more about the works, why not visit Bruce Gray's website at http://www.brucegray.com? You can find these afore-mentioned details in the second Movie and Television page.
This is the first episode where the "Jack handwriting" font is employed; Jack's name at the end of his email is written with it. The font was used in numerous episodes of the second season, and the show logo "profiler" is written in it as well. The font is called "Rougfhouse" and is manufactured by House Industries. Thanks to Nick Knight and his Jack-like hacker abilities for bringing this to my attention!
