You compare what she provided to what everybody else (you + the school) provided. So, it's no longer an issue.
But, there is an additional caveat. The assumption was that the fellowship was a true scholarship. If any of it was reported to her on a W-2 or a 1099-misc (box 7), because she provided services (typically research or teaching) then it is earned income and that part is considered her money providing support. A scholarship, reported in box 3 of a 1099-Misc, is taxable scholarship and not earned income.
