The person who Dwight had supposedly killed was trying to harm his brother—he tried to protect him.
As for getting along with others, Dwight is close only to the conspirators. He is a terribly loyal person, and they’re aware of that.
Unlike in canon!Dalton where he is brushed off, he’s got the “killed a guy” tag on his person, and people are wary of him, because they think he’s off the deep end.
The Twins use Dwight like a secret weapon—if there was ever a top hitman among Windsor, it’s Dwight.
He still hunts down those who are being evil, no matter what the species.
He was performing a ritual that was actually something that worked. His innate gift (even as human) attracted a vampire.
Dwight is in Dalton mainly as a punishment by the Houston clan. It really is his own fault. And he made a mistake that new ones (and old ones) should not do. He knows perfectly well why he's there. But they'll let him go sooner or later.
He turned someone, but you're not supposed to do that when you're new yourself. To add insult to injury...the person he turned was very young. Dwight's only statement on the matter was that the person he turned had been dying. And he refused to let it happen.
Alan was looking after his big brother during daylight while the human Houstons thought Dwight was dead. At the time, Dwight didn't know that there were vampiric Houstons (like Ford). This lasted about six months, Dwight getting stronger all the time. Then the vampire who changed Dwight came back. Alan, the poor thing tried to protect his brother by going after the vampire. He got severely injured. Dwight went into a fit of rage and fought the vampire back, and drew it away, but when he came back, Alan was dying. So he changed him-- Before Ford finally arrived to where Dwight was, killed the vampire off and then realized he was too late to stop Dwight.
All Vampires have the power to hear thoughts and send psychic signals to other vampires. If they're strong enough, their messages can cross continents.
Everyone is at Dalton to learn to get along with other clans and to learn much about their powers and history.
Dwight refuses to hunt people.
He'll be ripping into packets of medical blood every night.
The Vampires at Dalton feed off the day students.
Chaos herald. Very little control when let loose, so handle with care. Causes quakes, fires, lightning and cataclysms.
Dwight gets huffy when he's not allowed to use his powers.
Logan likes the idea of using Dwight's powers to make everyone stop fighting. He tried to convince Derek to go punch Dwight in the face, despite Derek not liking that idea. Instead, Adam overheard and locked eyes with Dwight, snapped his fingers and set him off. The earth began to shake, the sky darkened, lightening cracked and the earth rocked more. This continued until Kurt stopped time, saw Adam and went over, pushing Adam to the ground. Kurt then ran back to Dwight and hauled him into Blaine's barrier. Everyone was then ordered back to their houses.
