Canon: Left a trail behind him but was never caught, was Crucio'ed when Voldemort returned.
Post:
Avery was a man of few words. To be completely honest, most Death Eaters were. Macnair was only loquacious when he was drunk, Mulciber let out a few choice insults but preferred to snarl, Crabbe and Goyle would grunt, Travers would be too busy oogling Malfoy, and Avery could not care less about the rest of them.
This is hardly relevant to the description of Mr. Avery. It just goes to show that the quiet ones are the ones who should never be trusted. And Avery was one of the few Inner Circle members who would gladly put a knife in the back of one of their own.
This had more to do with jealousy and spite than any sort of perverse pleasure he could have gotten out of the killing. You see, there was nothing that special about Mr. Avery. He wasn't that descriptive, his attitude was more of the spineless variety, and he didn't much care to put in a lot of hard work or effort into the typical smash and grabs or pillaging. He did not 'pal around' with the other Death Eaters that much and, when he was around, there was generally something that piqued his interest.
Like women. Avery loved women. For that, he was teased by much of the Inner Circle.
"Goin' straight on us, are ya?" Macnair would be heard to holler.
"Gonna dissect her or fuck her this time?" That would be Mulciber.
"Avery's goin' prowling tonight! Lock your daughters up!" Notts.
Bastards. All of them. They had no idea of the beauty that was womanhood. Avery knew. Avery loved to cut into their arms and legs. He loved to trace their veins with his tongue and then with a scalpel. Avery so dearly loved his victims, especially the ones with long blonde hair and long legs. "They won't compare us to nazis if I'm carving into their Aryans," he had explained once.
No one had asked him for justification. They just accepted Avery's fascination as it was. But then, that was the basis of the Death Eaters. Their faults were accepted if only because it all fit into Voldemort's Big Plan.
If Avery liked to dissect, he'd have women. Women in the dungeons, women in the street, women everywhere.
The problem with Avery was that his tiny obsession became...not so tiny. An attack on Narcissa nearly caused him to be infertile for the rest of his life and, at that point, it was brought up to the Dark Lord that one of his own had 'a problem.'
Avery's condition was looked upon and observed and Voldemort soon found the perfect solution. A leash.
It came in the form of a fat brunette who looked like she would rather be eating out a woman than chomping down on Avery. Anything but Avery's usual type.
Voldemort tied Avery to this creature and soon, the 'big' problem became 'no' problem at all.
There was a loophole in Avery's psychosis. Not that surprising. If one looks closely, there is a loophole in just about everyone's psychosis. Even the immoral have their ethics and so on. The dilemma with Avery was that he, despite all appearances, had an unhealthy obsession with religion.
Now, Avery wasn't a Bible-thumper, in fact, it was safe to say he had only read the black book once in his life. Whether this was the new or old testament, no one had ever bothered to ask. The point was that Avery enjoyed religion, studied it, and let it become a part of him.
Of course, he did leave out the minor things. Such as 'Thou shalt not kill' and all that. It just did not fit in with his round of fun. So when he came across the adultery section, he came to the startling conclusion that adulterers pay heavier in the afterlife than murderers.
Well, damn.
Now Avery had a problem. He could continue with his lifestyle of raping and carving or he could settle back with his 'loving' wife. He chose the latter.
This did not stop him from killing people, especially women, but it did stop him from raping them first. The reprieve allowed him a chance to think before he committed anything, therefore his attacks were no longer random but timed and controlled. Voldemort would point and Avery would attack.
Simple, really.
Other than those few small details, there was really no huge difference between Avery and the other Death Eaters.
Save that Avery liked to curse. A lot. But that's a different story for another day.
Avery had taken to pacing the common room when nature hit. Being the logical thinker he was, he opted to find the local bathroom and relieve himself just in case Malfoy came in and needed them for something else. He told Macnair where he was going, again, just in case Malfoy came back. There were few things Avery feared. One was getting caught, the other was Voldemort, and the third was Malfoy's bad side.
Notts was on Malfoy's bad side. Look at him and you'll understand where Avery's coming from.
The gray-garbed man stepped out of the room, drawing his hood over his black hair and moved through the dungeons. Past schooling at Hogwarts told him where he needed to go.
A turn here. A turn there. A pretty young lady walking right there. Turn...
Wait.
Back up.
Avery did a double take and caught sight of..Lucilla? He recognized her from the Death Eater meeting they had before. "Miss Starstorm." His eyes trailed up her body. "Odd to see you here." She was with Voldemort's side. Therefore, she was now the enemy.
Therefore he could do whatever he damn well wanted with her. He moved into her path, blocking her view and her way. "How did you get in here?"
