Melanie Smith plays Rachel ("shrinkage"), who made out with Jerry in the audience of Schidler's List in the raincoats episode and for that reason her father forbade her dating Jerry. However, in the Hamptons episode they are dating again. 3 years later Smith also played Gul Dukat's daughter in Star Trek Deep Space 9 and there too her father hated Garak, who was seeing his daughter. I wonder if The DS9 writers saw Smith in Seinfeld. Several actors were in both shows. Jason Alexander was in the DS9 episode Think Tank. Elaine's psychiatrist was the Romulan Vreenak (In the Pale Moonlight: "It's a faaake!")
