Dr. Reston is Elaine and Crazy Joe Davola's psychiatrist. He's also Elaine's boyfriend. They are seen kissing, but Dr. Reston keeps ruining the moment by trying to remember if he left one of his patients (Joe Davola) an extra prescription for medication.
Upon their return from Europe, Elaine reveals she does not like being with Dr. Reston, and refers to him as her Svengali (she initially pronounces it «sven-jolly», before being corrected by Jerry and George) saying that he has a cheerful mental hold on her.
She decides she wants to end the relationship, but has trouble doing so, presumably because they have discussed much of her personal life and relationship history during her therapy sessions.
Elaine convinces Kramer to pretend to be her new boyfriend to help get rid of Dr. Reston, but this only leads to Reston manipulating Kramer into meeting with him. The plan backfires when Dr. Reston uses his abilities as a therapist to befriend Kramer. The two smoke cigars together and Kramer ultimately ends up recommending that Elaine and Dr. Reston stay together.
