The X-Files, Season 4

Scully:
Although cleared of any wrongdoing in the deaths of Amy and David Cassandra, Agent Mulder still has no recollection of the events that lead to their deaths. His seizures have subsided, with no evidence of permanent cerebral damage, but I am concerned this experience will have a lasting effect. Agent Mulder undertook this treatment hoping to lay claim to his past, that by retrieving memories lost to him he might finally understand the path he's on. But if that knowledge remains elusive, and if it's only by knowing where he's been that he can hope to understand where he's going, then I fear Agent Mulder may lose his course. And the truths he's seeking from his childhood will continue to evade him, driving him more dangerously forward in impossible pursuit.
