Leo had seen Tia Callida in action; she liked knives, snakes and putting babies in roaring fires. Yeah, definitely let's unleash her rage. Great idea.

Leo dropped into the pool and approched the cage. "Hola, Tia. Little bit of trouble?"
She [Hera] crossed her arms and sighed in exasperation. "Don't inspect me like I'm one of your machines, Leo Valdez. Get me out of here!

So, a crash course for the amnesiac,” Leo said, in a helpful tone that made Jason think this was not going to be helpful. “We go to the ‘Wilderness School’”—Leo made air quotes with his fingers. “Which means we’re ‘bad kids.’ Your family, or the court, or whoever, decided you were too much trouble, so they shipped you off to this lovely prison—sorry, ‘boarding school’—in Armpit, Nevada, where you learn valuable nature skills like running ten miles a day through the cacti and weaving daisies into hats! And for a special treat we go on ‘educational’ field trips with Coach Hedge, who keeps order with a baseball bat.

It'll be dangerous," Nyssa warned him. "Hardship, monsters, terrible suffering. Possibly none of you will come back alive."
"Oh." Suddenly Leo didn't look so excited. Then he remembered everyone was watching. "I mean... Oh, cool! Suffering? I love suffering! Let's do this.

Jason wasn't sure what to expect at the end--a dungeon, a mad scientist’s lab, or maybe a sewer reservoir where all Porta-Potty sludge ends up, forming an evil toilet face large enough to swallow the world.

The way Leo figured it, he spent more time crashing than he did flying. If there was a rewards card for frequent crashers, he'd be, like, double platinum level.
