Will:

Will wasn't sure what to think or do. More Lightwoods, was the only thought he could string together. He turned to look at Jem but he was just staring at the new members of the Lightwood, family paying no heed to Will.

"Tell us who you are!" Benedict yelled. The man's face was turning bright red.

Will smiled with pleasure at the sight.
"That's enough." Shouted Consul Wayland, putting up his hands for silence, but he didn't receive it.

"Can someone explain this before we have a full blown fight on our hands?" Someone yelled over the others.

Will leaned over to Jem, "Why would you want to do a thing like that?" He whispered into his ear. Jem, despite trying very hard not too, smiled.

"I'm going to kill him." The man named Alexander said under his breath, though Will doubted that anyone one alts heard above the shouting. His sister, Isabelle –who William tried his best not to look at- replied.
"I'll beat you to him."

"Everyone!" Yelled Wayland, "Please sit down." He said softer as the shouts turned to whispers, and from that, to silence.

"I love this meeting." Will whispered only to be swatted in the back of the head by Charlotte.

"Hush now William, please."

"Please explain this." Consul Wayland asked politely leaning forward so his whole torso was over the banister.

"What is there to explain?" The man who had been introduced as Jace Lightwood spate in irritation.
"Jace."

Will heard someone whisper, and by the tone of the voice he guest it was one of the women.

"We have told you who we are," Jace continued, "I am not sure who this man is, and why his gets to claim the rights," he hissed, "to the name of Lightwood, but we told you who we are and we need help."

Benedict opened his mouth but Wayland spoke before him.
"Forgive us young nephilim, we were just unaware that another family with the name of Lightwood existed outside of London. Where is it that you come from?"

Will saw something change in all their faces, but before he could pick it out they were all stone faced again.

"We hail from the Institute in south Africa." Alexander answered.

"And the Night Child?" Wayland asked.

The vampire stiffened, and stared at his feet. Will watched in amazement as the Fairchild girl, quickly but surely brushed her hand across the back of the vampires.

I understand why she's with the Lightwood, he thought disgusted. Then he thought of Tessa, her hand till in Jem's, the feeling of her lips and regretted the thought immediately. Who was he to judge her for being with a downworlder?
"Simon is from New York City."

From the corner of his eye Will saw Tessa's eyes widen ever so slightly. The vampire was from her home.

"He became an ally to us when we were there and well…" Alexander turned to look at the vam-Simon then turned back to Wayland, "He just sort of stuck with us."
"He's a friend." Jace clarified with a hard look at Wayland.

The vamp-Simon looked up at him in shock, as though being called the nephilim's friend was surprising news to him. Will understood why; downworlder and nephilim friendships are a rare thing indeed. Tessa –though accepted by the enclave- was proof that not everyone accepted those kinds of indiscretions.

Benedict looked as though he was going to fly strait through the roof, so did Gabriel. Will turned to look at Gideon, he didn't look angry, just shocked. Will had grown fonder of Gideon. It had only been a few weeks since he had moved into the institute but they all found him quite a pleasant fellow. Sophie, Will thought of her fondly. He had watched from the door as she and Gideon trained together the other day, -alone- and it made him even fonder of Gideon. He was sweet with her, never cross when she messed up, and was always smiling. Will had see in ever word, every look on Gideon's face that he was very affectionate towards their little Miss. Collins and he was thankful for it. Sophie deserved to have someone be sweet on her.

"Would you like to tell us why you have come today to ask the Enclave for help?"

Alexander opened his mouth to speak but his brother was louder and faster.

"We seek the knowledge of someone's whereabouts. We have reason to believe you might know where he is." He said.
"What?" The vampire looked at his companions curiously.

Apparently he was not in on the plain.
"We are looking for a warlock. Magnus Bane."

"OH NO WE'RE NOT!" Alexander yelled.
"Yes we are."

"Umm… Magnus?" Will whispered to the warlock behind him as the argument continued.

"Yes?"

He was answered.

"Do you what to… um…" Will trailed off as the conflict of the two -no wait, all four know including the vampi-Simon- grew louder.

The warlock leaned forward, his chin coming to rest on Will's shoulder, annoyingly.

"No." He said flatly, "I'm going to sit here and watch the show."

Wayland started to speak but he shut his mouth. Everyone in the hall was staring at them, no one knowing what to do.

Magnus started to sit back when Alexander shouted, "We are not going to Magnus! We will figure this out on our own. That is final!"

Magnus froze, and Will felt him tense behind him.

"Do you know them Bane?" Henry asked, "Well, they know you."

Will hadn't heard Magnus answer.

"Look, it was your stupid, glittery warlock that got us into this." The Lightwood girl –Isabelle- said to her brother. "He-"

"Mute point." Interrupted the Fairchild girl, her eyes were staring past Will to Magnus. Her eyes were wide, her face as white as snow.

"And why is that Clarissa?" Alexander Lightwood threw his hands up in frustration.

Her eyes never left Magnus, "Well…" Her voice faded away as the three other nephilims and the vampire turned to her and their eyes found Magnus.

Alexander looked as though he was about the throw up, while his siblings looked amused.

"Well…" the vamp-Simon just shrugged, "Found Magnus."

So I don't know why but I don't think I was able to capture Will's character as well as I am the others... sorry for that, I 'will' ;) try to do better.
