Week 25- I have a DeLorean

Alright so one day I was walking in the streets of Chicago (one week from today), and suddenly a beautiful DeLorean strode up next to me. The man named Stone, what a coincidence, told me he had urgent news of the senior trip. He told me I had to make sure Jesse yelled as frequently as he did at the beginning of the year. He told me that when we were on the trip that since he didn't yell one time, Ethan was murdered. He had no time to explain and zoomed off into what looked like nowhere. I completely disregarded him because I thought he was a psycho maniac. Turns out a few months later he was right and Ethan was tragically killed.
