The X-Files Quiz

Everything about the main cast of The X-Files, the drama about two FBI agents assigned to the Bureau's unexplained cases, one who believes and one who does not. The set covers the whole run as one cast: the original nine seasons and the two that followed years later, taken together. In scope is the main cast, the performers the series credits in its starring and also starring tiers. Recurring players and guest stars are out however memorable the role, and this show has more memorable guests than most. The two feature films are films rather than seasons, so a performer whose only appearance is in one of them is not an answer here. Every answer is the performer, not the character. Cast taken from the Cast and characters section of the show's Wikipedia article, corroborated against Wikidata. Nothing in this set gives away the story: no question, clue, option or answer reveals what the conspiracy turns out to be or how anyone's story ends.
