You're Archie's girlfriend and weren't always the jealous type but one day you snapped.
"Oh hey"
"Y/n! It's not what it looks like!"
"Oh really? Let me guess, another one of you're 'friend hugs'?"
"Y/n I wouldn't ever be with Archie, I know he's yours"
"Fine then explain what is going on here"
"Betty's having a hard time at home and I was comforting her"
"Ohhhh... sorry about that. My home life isn't so great either. I'm sorry for assuming"
