"Cersei...will you go to prom with me? Pleeeease?"
"We've been over this before. You know I can't. You're my brother. What would people say?"
"Well, why does that matter? People will just think neither of us have real dates."
"Our parents are cousins! People already make incest jokes about us for that! Can you imagine if we went to the prom together?"
"Well, to be fair no one would know our parents were cousins if you had just done your genealogy project yourself rather than pay the nerd to do it for you!," he defended.
Cersei's face turned red as a beet. "Well, perhaps you should have done the project for me then! Baelish wouldn't have gotten such info to spread if you had!"
"I'm nearly a straight D student! I was doing you a favor by refusing to do your assignment!"
