On page 170 of Q&A, Q is bothering Picard and Crusher about their past romantic affiliations, and the final form he assumes is that of Marta Batanides. Afterwards, Crusher asks Picard who the woman was. Picard tells her that Batanides was an Academy classmate of his, but Crusher says she doesn't recall Picard ever telling her about Batanides. But in Section 31: Rogue, Crusher meets Batanides, and on page 51, Crusher herself slyly recalls that Picard and Batanides are old friends.
