In the Mark of Athena, the radiated power actually repels Arachne's children from crawling on it. SO my guess is that, like Percy and water, her "powers" will be amplified from the power of the Parthenos. Also since the statue being recovered will end the Greek-vs-Roman rivalry there might be a chance that the Gods become on with their two sides instead of split.
