High school AU implied underage SladeJay and SladeDick.
Slade's a teacher who is believed to sleep with his students. He will sometimes pick a student and poke fun during class and keep them after to study.
After Bruce gets called saying that a teacher is keeping Jason after class and they were worried so he should talk to him about it. Jason denies it and says "Mr. Wilson" and that worries him more because he got the same call about Dick when he was in high school (but Dick assured him that he wasn't sleeping with Slade but he was blushing)
Jason told Bruce "he wasn't screwing "Mr.Wilson" he was screwing his daughter" and it was just something to scare the kids that dated his children. Dick didn't say anything because he wasn't out at the time.
