By the time Gwen stopped growing she was 20 feet tall. The girl was only just above her knee. Gwen stared down at her.
"Now if I was you I would run away and not look back," said Gwen. "Or else you'll see the dark side of me."
The girl finally ran with these words. When she was gone Gwen went into an alley to calm down and to stay out of sight.
When she was calm she concentrated on shrinking and sure enough she began to shrink down to her original height. She was relieved and she hoped that no one else had seen her in her giant form.
Gwen stepped out of the alley and she walked down the street back to her house. She wasn't sure what she was gonna tell Ted. She wanted to keep her size changing powers a secret but if she kept slipping up like that she could get exposed.
When she got home Ted was out doing some food shopping. He had left a note telling her that he would be back later.
This was a huge relief for Gwen and she went into her front room to watch some TV.

What's on?
