Penny learns the truth

Penny couldn't say a word as everyone continued to tease her and laugh at her. Then Penny started to think. She finally remembered what she had done to Grace. And then she realized the truth. "It was you," Penny said all of a sudden.

"Excuse me?" Grace asked.

"It was you who made me wet the bed, wasn't it?" Penny demanded.

Grace snickered and smiled. "Maybe at first it was, but today, last night, I did absolutely nothing. That was all you, little Penny. You can blame me all you want, but nothing will change now that you're just a baby stuck in an adult's body."
