The Gallaghers are an old English family, one of the most important in the entire Great Britain. They are known for following the strict old patterns of pureblood, considering most of those whose blood is not entirely pure of inferiority, although they don’t display their thoughts, concerned about what the Ministry of Magic could take from this affront. Emmett’s father is half Gallagher, half Achens, another old family, this one from Germany, where the roots of prejudice against those without pureblood is even stronger. Albeit the common acknowledge of both families opinions when it concerns the mixture of bloods amongst the wizards, they didn’t choose places in none of the wars, choosing to stay as neutral as either the results – purebloods winning or equality winning – wouldn’t bring them down.
The Murphys are an Irish family completely opposite to what the Gallaghers and the Achens represent. Not only they are a very wealthy family, their entire support has already been towards the equality and they fought for that side in both the past wars. It was unlikely the match between a Murphy and a Gallagher, but Edmund and Annabelle first met in Hogwarts and decided to give a chance to their marriage.
Emmett is the only boy in eight kids, and that was something that always bothered him. By being the only boy, the entire family expectations are on his back and his father expect him to become something big and important. Although his mother absolutely despise the dark arts, what made her plan on sendng all her daughter to an school abroad knowing that Beauxbatons wouldn’t offer any sort of training involving those arts, his father considered sending Emmett to Durmstrang – old habits die hard. His mother was absolutely against, and at first his father didn’t bother that much, but as the years passed, Edmund was constantly teaching his own son everything he knew about dark arts.
Emmett is not a bad person, really. He won’t use everything he knows on you just for the sheer pleasure of it, no. He will use it if he thinks you deserve it or if the situation requires him to do it. There are a few people Emmett really care about though, and those are specially his sisters and his mother – he wouldn’t hesitate before hurting anyone who messed with them, but he wouldn’t allow anyone to know he has this loving and caring side simply because his father has always taught him that emotions were more likely to hesitate, that emotions were the easiest way of breaking you and tearing you apart.
He doesn’t really do friends. Not that he abominate people who have them, but he prefer to stay away, no strings attached, as the more people you love and care about, the weaker you turn out to be, and weakness is a trait he grew up to despise. His rare real friends are people he has chosen to believe will never go away. He doesn’t plan on falling in love or having any sort of relationship where he cares about the other person – ever. He would rather have a marriage for convenience than a marriage for love because he can’t stand looking at how fragile and weak his father appears to be when he’s close to his mother. It’s ironic even, how the person who always taught him not to get attached, not to have feelings towards anyone was exactly the person whose biggest weakness were the people he loved – you live and learn, after all.
What his boggart means is that his biggest fear is of not succeeding, of disappointing people who are counting on him, like his entire family. He knows really well that his mother would always stand up for him but he’s afraid of what his father might do in case he fails at life, fails at being someone successful, even if that mean he would’ve to pull aside the basic necessity of being happy. That’s why he prefers not to have friends or relationships – they can manage to put your focus out of your main goal, and this is just not acceptable.
He’s extremely intelligent and meticulous, always paying attention on details. Abigail used to joke that he had OCD when he was a kid, but he never was diagnosed with it, which was actually a big surprise for the entire family – he was just neat, a trait that belongs with people of his astrological sign. When he doesn’t manage to make something perfectly, he feels extremely disappointed with himself, which causes some anger issues that took him a lot to learn how to control.
