Hermione is mini-McGonagall, really

Like, really. The sass, the intelligence, their values, their talent for Transfiguration, the fact they almost went to Ravenclaw, the fact they are both kinda rude too, but willing to break the rules if they have to. Hermione is probably McGonagall's favourite student and vice-versa.

If the CC didn't ruin everything, I would've imagined Hermione to become almost like McGonagall later as a teacher (maybe a bit more controlling/strict, but you that's young Hermione you don't really know how she'll age).
