Peyton Ellis is a girl that appeared in The Third Wheel. Greg explained he had a small crush on her. When she was drinking water from the fountain, Greg went in front of her. She knew Greg was going ask her about the dance, so she kept drinking until the bell for the period rang. Greg thought he stood there like a dope.
