I also believe this, he didn’t even have a proper senior picture and I remember that was always the big threat in high school - “you keep this up and you won’t walk” - kind of stuff. Pat of course being an asshole was probably proud to not walk since he hated everyone in his class. It’s not a big deal to not walk with your friends if you don’t have any.I bet he had to go summer school every year to make up for failed classes. I wouldnt be surprised if he didnt even walk the isle in graduation because he still had credits to make up over the summer and graduated late.
