Finally, "shippers" (fans who would love nothing better than to see Mulder and Scully act upon their feelings for each other) get a heavy dose of the usual sexual innuendo and lingering, tender glances between the attractive costars. Mimi Rogers and Luke Wilson incite palpable jealousy between the leads; the appearance of a wedding band on Mulder's hand in a back story hints at stories not told; and the usual extreme and dimly lit crises illustrate just how far Mulder and Scully will go for each other. In the end, the complexities of their relationship may be the most tense and intriguing of all the mysteries explored by this epic television series. --Eugene Wei
