There's a Demigod at my school

I may be jumping to conclusions but so far the evidence is pointing in the true direction. So my friend is ADHD and dyslexic. Big sign right there. But I guess it could be a coincidence. She also lives with her mom and her dad left before she was born. Am I right? Is this too much of a coincidence? Is she really a demigod? If so what god do you think is her parent? Btw she's a really good artist and musician. So comment what you think!
