Dudley already have a small suspicion that Sam is a wizard, after all he grew up with Harry,so it would be easier for him to spot the signs than a normal muggle. P.S. Petuna will have kittens.

Beautifully done. I can actually imagine Petunia already knowing about her grandchild's magical gift and just too sad to talk about it, but resigned to the fact. Dahlia could even be magical too, conceivably.

Who knows why Petunia turned out to be a muggle (squib?) while her sister was a witch, and the magical ability skipped Petunia's child as well... only to show up in the next generation? Genetics is such a mysterious science.

Excellent story.

I suspect Dudley will be less surprised than Harry thinks.

Wonderful story and yes I do vote for a sequel as well. You have a way to focus on the small things that give a story depth and feel very realistic. I really am curious how Petunia will react when she knows she has a magical grandson. I hope she understand that she has passed on the magical gene, even if she's not magical herself. I always had the idea that marrying Vernon was for her a way to keep up normalcy as much as possible so maybe she is a bit more free to embrace magic now he is gone. I hope you'll let us know what happens next.

Very clever! Brace himself, indeed. And maybe meeting little Al might help Petunia cope when she eventually  learns her grandson is magical  as well. Sadly, even though she was polite, I can forsee a bit of Petunia and Lily playing out between Sam and Dahlia in the future.

Nice read. I always thought something of the sort should happen to one of Dudley's children--both as payback and to show Petunia that yes, she was special too (because even if she wasn't a witch she passed the trait on thru her line).And I agree with the others, this certainly could have a sequel.  Thanks for sharing.

I really think you need to continue this story.  It would be great for Harry to introduce Sam to the wizarding world.

What an exceptionally lovely story.  Powerful in its simplicity, characterizations ringed so true-- that it even evoked a moment of empathy for Petunia.  Brilliantly done!!!

I'm sure Big D has to know already. Perhaps that's why he told Sam about his cousins and probably told him not to let Petunia or Vernon see. I really get an image of Petunia looking at Al and seeing her sister at a similar age. A brilliantly crafted moment, there.

Loved it. There is some poetic justice there; Petunia migth have shunned her nephew for being a wizard, but will she be able to shun her grandson, not to mention will her son accept it? Very well written story.

Great one. You do post war really well. Wonderful to see something new. Cheers.

Oh my, what will Dudley think of that.  Great little story.  You know there is a sequel in there don't you?  Sam and Al at Hogwarts together. lol

I like how Albus almost acted as an intermediary. :)

Dudley may not be quite as surprised as Harry thinks.  But it just may finish off Petunia.

Very nicely done! I like the closure that Harry gets in his relationship with the Dursleys. And I loved the twist at the end!

Great story!  I was going to read 'Family Tendencies' when I saw your note about this story, and I'm glad you left that note because it's made reading the sequel so much better!Beth

What a twist! You must be tired of being innundated with my reviews but you deserve it! Any plot bunnies involving this young guy sam here? Even if just mentioning his name in passing? ;)) I really liked your ending to this ff ;)
