Greg is a student at Bayside High.
Breaking His Arm
When he overheard DeVante on the bus telling Aisha and Daisy about how their economic status separated them from the other Bayside students, Greg poked his head over the seat to tell them that when he broke his arm, he didn't tell his parents for a week because he was worried about how much it would cost.
Mac Pranking Gil
When Mac pranked Gil using The Pharaoh's Tomb, Greg was among the crowd of horrified onlookers as Gil emerged from the bathroom. They were further horrified when Daisy came to them and revealed that Gil was a spy from Valley.
