Friendship is a common theme in many YA stories, especially theHarry Potterseries of books and films.

But what can’t be denied is that the three definitely stick together.

Or at least, in most situations.

Harry and Ron (disguised as Crabbe and Goyle) and Malfoy in the Slytherin Common room in ‘Harry Potter and the Chamber of Secrets’

But that doesn’t stop them from developing a bond.

The two are often seen helping each other out with spells, despite their very, very different interests.

McGonagall was Head of Gryffindor House and taught Transfiguration, but she was also among Dumbledore’s closest friends.

Though, they were both very compassionate and cared deeply for each and every one of their students.

All in all, their importance to each other was easily observed, even after Dumbledore’s death.

He also happened to be the one to transport an infant Harry to the Dursleys' house.

So, when the two reunite later inHarry Potter and the Philosopher’s Stone, they instantly become friends.

Who says siblings can’t be friends?

The two are so perfectly in sync that it’s pretty much impossible to picture them apart.

They’re inseparable, and rarely share a scene without their other half.

Whether it’s setting off fireworks during an O.W.L.

The Map speaks to their love of causing trouble, but also of sticking together.
