Ahem, why exactly that we can't choose albus. Yeah sure he only showed up in epilogue scene. But it sure enough to estola my puso with his cute, shy attitude and how his relationship with harry is so sweet compared to james sirius potter. Renesme doesn't pick my interest. At all. I wish jacob ended up with leah anyway, so I think renesme is annoying and uneccesary..
Or because they don't believe she should logically exist because they either wrongfully think that a man needs blood circulating in his veins to... you know (which he does not. Many humans have done it without) or that the non poisonous venom should somehow kill Bella.
Or they just want to click on Harry Potter options all day.
Honestly, Albus didn't do a single thing but be talked to and get on a train.
