Re: mark reilly
1. Popcorn. Too much grease with pizza.
2. He would have been so much calmer. He would have been much better-liked in high school, for starters. More reliable, more sober. He'd have been a better boyfriend to Vic and probably would have tried to make it work even after high school (though whether it would have or not is anybody's guess, Mark got insanely busy after graduation). Obviously he wouldn't have gone bugfuck crazy at any point in time. I would even guess that his personality wouldn't be so addictive, and a whole lot of things would have gone much easier for him in general.
