If villainess us the route, have her continue to be clever. She undercuts relationships. Gives details, but nit whole truths to hurt people, but she filters it through several layers of deniability. She even has the time turner. Make it so that she's the actual reason Buckbeak hurts Malfoid to drive a wedge between her and Harry. She gets Hagrid in trouble. In fact, make her actually a sort of opposit to Voldemort, she hates magic, witches and wizards and is only playing along since it's the most effective way to subvert it all.
@DodgerWing True, but we're also getting alternatives like Competent Lockheart. Maybe, since we're bringing back yearning, just maybe Hermoine can just be a different type of personality a man could yearn for?
@Critical_Scribe The 90's sequel trope were the protagonist has to have relationship troubles with their spouse, child/children or both. It was annoying.
