Yuuno having Alicia run simulations to figure out his chances of survival when Nanoha finds out that "Vivio" kissed him. Every one ends in Starlight Breaker.
After Subaru is kissed by "Teana" and the real one comes back:
Seargent Bennings: There are two individuals below, engaged in something like a wrestling match. Lt. Tuttle: Um, Sergeant, are you sure that's wrestling?
Arisa heckling Nove during the Mages vs Cyborgs baseball game.
Nove (thinking): What the hell does a broken ladder have to do with this!?
The final chapter is the wedding of Nanoha, Yuuno and Fate and hilarity ensues as everyone attempts to get ready.
Fate: "If I took both your names, would that make me Fate Testarossa Harlaown Scrya Takamachi? Or perhaps Fate Testarossa Harlaown Takamachi Scrya? Fate Scrya Takamachi? Fate Takamachi Scrya? Hmm, I need to think about this..."
Note that they spend the entire time from proposal to wedding in a daze trying to figure out the proper name order.
The hilarity that is the Nanoha and Fate Togetherness Alliance (formerly the Nanoha Worshipers and the Fate Fanatic Fanclub), a group of obsessed kids who hang out in a torch-lit basement wearing hooded robes try to mess with the wedding by placing a curse on the groom. Instead they end up making Vice uncontrollably grope every woman he sees (except Alto) and force Yuuno to speak in rhyme for 72 hours.
