Shenanigans ensue when a dating game takes place at the school, with a special bounty placed on Lelouch.
Circumstances bring Lelouch and Shirley together and they officially become an item.
But the next day, V.V. deploys a geass canceller and all of Shirley's memories return.
Oh god, now I have to backfill about Jeremiah, who I've been ignoring.
Jeremiah was a Knightmare pilot. He was disgraced when Zero freed Suzaku. He and Villetta compared notes about lost time and that's what helped Villetta realize Lelouch was involved.
