Phosphene

It's canon at this point that they actually were very good students, especially in Charms, Transfiguration and Potions (Flying too obviously), so good in fact that they created an entire supply of new products at 17.

We also know that at least Professor Flitwick was incredibly proud of them for that, and I bet that Minerva 'Mother Cat' McGonagall took one look at their achievements and became really excited because she always knew they had it in them.

(And the only reason Snape wasn't is because he hated everything with red hair.)

I also like to think that even if they did play pranks on their teachers, Fred and George were usually quite respectful to teachers they liked.

They might know each other's every secret because they're incredibly observant but you're dead wrong if you think they will ever tell a soul.

They protect each other fiercely because they know that mistakes stick with you much more than achievements.

They support each other through struggle without ever really addressing it because they know that admitting weakness out loud is difficult.

Ok, first of all, please don't yell at me. I don't actually mean this as an insult or am trying to bash her. Hermione is awesome.

But just as any Harry Potter character she has flaws to overcome, one of them being that she is indeed a know-it-all (though Snape had no right to call her out for it).

She actually gets rid of that bad habit very quickly, but there are some times where she's almost condescending towards Harry and especially Ron.

It's literally their first week of school when she calls out Ron for pronouncing a spell wrong, basically mocking him for it.

Bill was eleven years old when the war ended, which probably means he witnessed quite a bit of it, especially towards the end.

Luther = Luisa (the 'strong' one, actually under a lot of pressure, trying to be perfect to the families leader)

Diego = Mirabel (always in other's shadow, tries to win other's approval)

Allison = Isabela (perfect on the outside, but doesn't feel happy with her life)

Klaus = Dolores (cheerful, gift that can be too much)

Five = Bruno (troubled by knowledge of the future, left his family but loves them dearly)

Ben = Camilo (sweet, a bit sarcastic, sometimes forgotten among the others)

Vanya = Pepa (emotional, very strong gift she has trouble controlling)

+ Bonus:

Five = Abuela (asks a lot of his family, does it to protect them)

Ben = Bruno (watches his family from a distance, very sweet)

Vanya = Mirabel (the outsider, no powers, key to disaster)

Allison = Isabela (seemingly perfect, but doesn't feel happy with her life)

Klaus = Bruno (powers are more of a curse, isolated from his family)

Luther = Luisa (strong one, feels responsible for everything, struggles with not being needed)

Ben = Pepa (can't always control his powers, overwhelmed by them)

Diego = Camilo (hothead, likes to tease his siblings)

Five = Dolores ;¬) (knows more than the others, doesn't tell them)
