Johnny & Izzy
"It will," Johnny insisted. He was always right. If always meant almost never. "Trust me. I've seen babies."
Piper had a baby, and Piper was Johnny's family here as much as anyone. He liked going over to hang out and play cool big brother/uncle. And he'd seen his pseudo-mom get puked on plenty of times. If it happened to her, it was going to happen to Izzy.
