WMG / It's Pat!

Pat and Chris are bisexuals

When Pat and Chris first meet, it's love at first sight, with neither of them showing signs of wondering what the other one is. These are characters who nobody else can figure out the gender of under normal circumstances. Perhaps they actually didn't know what the other was, but being bisexual, they were both willing to date each other anyway, figuring they'd eventually find out once they had sex.
