Tybalt does not determine who gets a tuition or scholarship. He could only prevent it if the MC beat him. What actually speaks against this is Tybalt blackmailing Jill, which would then lead to a stalemate. But if the MC is not with Jill, she could lie to him. So I advise M/J fans to keep their hands off Jill.
If the MC didn't screw Sage and Jade, it shouldn't really bother Stephen. Still, it remains Stephen's choice. Jade and Sage could be advocates for Maya.
I see this as DPC ending Maya's father drama one way or another. Whether that's through Stephen's tuition or by releasing Patrick's money, I don't know either.
