Sy follows and takes pictures of Bill's young daughter, and sends them to Bill as a threat. Sy comes to hate and envy Will, who has everything Sy longs for, yet does not seem to appreciate what he has. Sy surreptitiously places photos of Will and his mistress, Maya Burson (Erin Daniels), into a packet of photos that Nina was scheduled to pick up at SavMart, in order to make her aware of her husband's infidelity. While inspecting his photos for the last time, Sy discovers that Will is having an extramarital affair and his idyllic conception of the Yorkins as the "perfect" family is shattered. The next day, his boss Bill (Gary Cole) fires him for a large amount of inexplicable additional prints. Nina asks Sy personal questions about his life, realizing that he is a lonely man, something only Jake had noticed earlier. Sy eventually manages to spark a connection with Nina when he pretends to be interested in a book he noticed she purchased in the store. He is painfully shy and socially inept, however, and his attempts to become closer to the family are gently rebuffed. He fantasizes about being a member of their family and sharing in the love he assumes they feel. Sy secretly makes his own copies of the Yorkins' photos from the film negatives and then puts them on a wall in his apartment in a massive collage. He idolizes their happiness and affluence, memorizing every personal detail about them. He has developed their photos for years and has developed an obsession with the family. Sy's favorite customers are the Yorkin family: husband Will (Michael Vartan), wife Nina (Connie Nielsen), and their son Jake (Dylan Smith). His work is his life as he has no one and nothing to go home to at the end of each day he spends his evenings sitting alone in his barren living room, watching television. Every day, he labors to ensure his customers get the best quality photos possible. He leads a solitary life outside of the "heaven-like" hyperreality atmosphere of the department store.

Seymour "Sy" Parrish (Robin Williams) is a photo technician at SavMart's one-hour photo developing clinic. The ticking time bomb of Williams' comedic prowess may lend Sy a deeper menace amid his outburts, but the quieter side of this performance shows Williams can give so much to a layered antagonist like Sy.Spoiler warning: The following contains plot details about The fact that Sy just wants to envision himself in a happy family, where he's the Yorkin patriarch, makes this all the more sad on top of everything.

He then forces Will and Maya to pretend to do explicit things to one another while he takes pictures of them, tragically mirroring the actions of his father who took photos while molesting him at a young age. When Maya (Erin Daniels), the other half of Will's extramarital affair, says she won't participate, he responds with a sudden and viscous "I'm not asking! I'm telling!"

The way he tells Will he's gonna stab him in the heart gives you the impression that he has no hesitation over this action, even though he has no inclination to do so. Going full=stalker mode, Sy tracks Will and his lover down to a hotel room, where he interrupts their get-together with a knife. It's not enough that Sy has covertly made Nina aware of the affair - he feels the need to do something about it himself.
