In many of these fanfictions, the event of Snape saving Harry from Umbridge is a turning point. Harry, who has always been at odds with Snape, is now in his debt. This changes the power dynamic between them. Snape may use this to his advantage, perhaps to get Harry to do certain things for him in the fight against Voldemort.

She might be tempted to continue her oppressive ways, but the knowledge of Harry's abuse could also nudge her towards redemption. This could involve her making amends with Harry, or even joining forces with him against the real threats in the wizarding world.
