Lois & Clark: The New Adventures of Superman Season 3 Episode 18

Forget Me Not

Lois has now amnesia, and Clark puts her in a clinic. But Dr. Maxwell Deter's treatment has extremed methods, one of them is that Clark can't tell Lois they are engaged and love each other. And another doctor is programming patients of the same clinic to kill people that he has been hired to kill (Perry is in the list). Later, Dr. Deter restrits Clark's visits to Lois because he wants her love. When Lois remembers only her work partnership with Clark, she tells him that she's in love with Dr. Deter.
