Picard/Q. Q has come to tell Picard that he will no longer be testing humanity. Oddly enough, Picard finds that he would indeed miss Q if he never saw him again, but he'd rather not tell Q why. Picard/Q pairing. Some rude words but nothing explicit. Probably my favorite of my Picard/Q works.
beautiful au where there's no q war and q just keeps randomly appearing in enterprise's adventures he basically lives there and does this every tuesday (he's a disembodied voice in picard's head sometimes)
