Dennis couldn't help the color that rose in his cheeks at that. It seemed like a compliment. "I like being counted on." It was definitely preferable to everyone else thinking he was still just a child with some issues left over from the war.
"I think I just want to go home for a little while. Still have two more years here before I graduate, I just want to get away for a little while." He was hoping a summer at home would leave him ready to come back for another year. Preferably a year where his own year mates were with him so he could have his friends back and his dorm full of familiar faces again. Also where he wasn't completely trapped by Death Eaters and a dome that wouldn't allow anyone out.
Dennis knew he didn't have the ability to leave the grounds or Hogsmeade during the school year, but having so many people trapped who did have those privileges normally really did a number on everyone's nerves. The trapped feeling spread to everyone, even those who didn't have a choice in the matter. "Are you doing anything fun?"
