Oubliette follows the story of a girl who was abducted and a woman across town who collapsed and muttered the exact same words the abductor says at the exact time of the abduction. Mulder and Scully investigate this bizarre connection. A poignant line towards the beginning of the episode is when Mulder is talking to the mother of the abducted girl, Amy. Mulder says, "I know you must be feeling..." When the mother interrupts Mulder and exclaims, "I'm sorry
but how could you really know how I feel?" Mulder says nothing in reply. It's powerful because Mulder does know the feeling of having someone close to him abducted. Mulder separates the events of his sister's abduction from this case and manages to make a connection with Lucy, the woman who has the bizarre connection to Amy. However, when the police and Scully suspect that Lucy was involved in the abduction, Scully accuses Mulder of allowing his sister's abduction to cloud his judgement. Mulder responds by telling Scully, "And not everything I do, say, think, and feel goes back to my sister." And this is what made this episode special to me, Mulder's emotional connection to Lucy. He truly wanted to help Amy AND Lucy to "escape". Scully finally realizes this at the end. "Mulder, whatever there was between them, you were part of that connection." David Duchovny gives a great performance that you shouldn't miss.
