Hunter definitely knows him because of Elle. Not sure what Everett thinks about his and Elle's relationship, but he hopes it's obvious that he's irrevocably in love with her so /shrug
Eli says HI BRO. Also, my only real headcanon here is that they're all pretty close in their own way and his brothers tend to drag him out to the bar whenever Eli gets too withdrawn. Also I said that two birthdays ago the brothers made Eli go to a strip club because they thought it was hilarious.
Potentially new friends with Leo? They're close in age and, eventually, he'll know him through the inevitable Tessa friendship. :3
Stella likely had a big ol' crush on him in high school but she was a year younger and didn't run in the same circles, so that was all super secretish, yet obvious in the way that high school girls usually are lmao. She'll make him food and things. ;)
He and Oliver should have def run in the same circles back in the day considering they were both athletes back in the day and Oliver is only a year younger. So they should be friends!
He could have been a big influence on Cash, maybe? Since they both had the career-ending injury thing and Ev was his guidance counselor?
Friends with Annie! Since they both work at DHS in different capacities. :3
I also need more friends for Zeke soooooo there's that :P And Mikhail. Which would be hilarious because reasons. LOL.
AND lastly TESSA. omg she's going to have a lot of emotions when she realizes a) she's not alone and b) he's MAJOR of all people. Here for it!!!!
