Lucky finally cracks under the strain of his secret -- but Veronica Mars is on the case, with Keith, and while they haven't quite solved for X on the bus crash, they're getting closer to why (and Woody) thanks to a blackmail recording and a...health final exam? Meanwhile, Aaron Echolls's trial is dragging everyone through the sociopathic mud, and the chlamydia a pitiless universe saddled Veronica with in a previous episode comes back to haunt her -- but not only her -- in a big way.
