Lucky Strike

When Principal Li fails to honor the raise promised in the teachers' contracts, the teachers go on strike. Substitutes are hired to take their place, including a spaced-out elderly woman to take over for Mr. DeMartino; and a sleazebag for Mr. O'Neill's class who is soon fired for hitting on Tiffany. That substitute's replacement is none other than Daria. Quinn starts to fear that the truth about her sibling relationship to Daria will come out, especially when she keeps having to defend Daria in front of her friends. Daria tries to teach the class Shakespeare's "Romeo and Juliet", and when she assigns a test, Quinn finds that she knows the play well enough to ace it. When Quinn gets a much better grade than the rest of the Fashion Club, Sandi brings up the question of Quinn's relationship to Daria. Quinn finally admits, with no shame, that she and Daria are sisters.
While the strike is going on, the Lane siblings end up helping the teachers.
