Huge fan of pink haired one & forgive my forwardness; Harry is much better suited for Nymphadora than Remus. He'd never ditch her. And before you say anything, yes she is 6 years older than Harry but Remus is 12 years older than Tonks. And this coming from a diehard HARMONY fan.
Harry is the head of two Houses so he could marry Hermione as Lady Potter and still marry Nymphadora....owww! I'm sorry I meant Tonks. Please don't hex me again. Anyways Harry can still marry Tonks as Lady Black.
