The Cube Rule

Penelope stifled a laugh. That was such a Percy thing to ask. She could make something up just to mess with him for asking a weird question or she could be serious about it. In the end, she settled on the latter. 

"Right now I think it's about 75%. If our next date goes well, that number might go up to 90%. Happy?"

"Quite. I only asked because I wanted to mentally prepare myself to interact with him in the future if necessary. The odds do seem in his favor at the moment so I'll have to prepare a list of questions for the next time I see him," Percy replied. 

Penelope smiled and shook her head indulgently. Her brother knew he wasn't so great with people. He normally didn't bother to try with them because he couldn't be bothered. But if he was willing to go to this extent to prepare a proper interrogation, he couldn't be completely against the idea of her dating Roman.
