One cloudless afternoon, Utterson Jr. and Enfield Jr. were out in the yard throwing football when a sparkling red sports car zoomed by and slowed to a stop in front of the house neighboring Utterson's. A young boy with nice clothes and slicked back hair hopped out and introduced himself as Henry Jekyll.
The boys began to talk and they soon learned that Henry was in their grade and will be going to their school the next day. They asked him to throw football when all of the sudden, "the smile was struck out of his face and succeed an expression of such abject terror and despair as froze the very blood of the two" boys standing in front of him. He turned his back and walked away.
Mr. Lanyon introduced Henry in front of the class the next day but something looked different about him. His skin looked pail and his eyes were a weird color. He looked afraid and sick.
The next day at school Utterson noticed that Henry looked angrier than the day before. When class was over Henry bolted out of the room to his locker. Utterson knew something was wrong and being the nice, polite boy he was he went to check on Jekyll. When he approached him, Jekyll turned and took off towards the door.
Henry continued to storm away and he trampled another kid when doing so. He ran all the way home.
The next day, Utterson walked to the bus stop super anxious about Henry. When he got there Jekyll looked just like normal again. He even greeted Utters super politely. Though he was very confused, Utterson was happy the old Jekyll was back.
