These two episodes of Veronica Mars were quite a combo platter of silly high school plots (mascot-stealing in "Betty and Veronica"; petty harassment in "Kanes and Abel's") and some pretty major progress toward solving the mystery of who killed Lilly Kane--as well as the related question of where is Veronica's mom. She's in rehab now! Next: S1E18, "Weapons of Class Destruction," and S1E19, "Hot Dogs."
