Zed tried his best to keep up.  He signed up for this and he won't fail.  He will learn and he'll improve.  He followed the instructions of Mr. Valdemar.  Veins started to show up on Zed's skin as his muscles tensed up.  With his eyes closed, he evened out the flow of power to maintain the offset balance caused by the sudden shift.  He knows that he is strong and in front of Aine, Mr. Valdemar, and Mr. Zasso, he will prove this.
