Think of ones to do for each year and how it could be done for 5th, 6th and maybe 7th. It would help if what situation could happen.
But here are some people I won't do and the reason why.
Tonks because I like her with Remus though if say they ask Harry to make Tonk pregnant because Remus is scared about having a werewolf baby.
mcgonagall, Sprout Or Umbridge the first two kinda to old in appearance but they're could be a maybe. Umbridge need I say anything.
Please place ideas in the Review.
