You decide to leave it alone, but she's clearly agitated. Moira tosses the Frisbee so hard at Isabella that she jumps away from it with a scream.
"Come on, Izzy! It's not a snake!" Moira shouts, with a hint of agitation and glee in her voice.
"No...I'm done. I'm not sure what your problem is today, but I'm out!"
Isabella storms off, toward one of the shelter houses. That's definitely not like her... you say to yourself.
"One on one?" Moira asks, looking at you. Before you can answer either way, she's picked up the Frisbee again, and hurls it toward you with the force of an angry god on crack.
You take a direct hit to the face.
