Creeping into the Institute was a hard thing to do.

Even more so, when your sister and everyone else you know is practically the lightest sleepers on the planet.

He could not blame them. Alec was the worst, in terms of being light sleepers.

Alec's key clicked in the lock- a sound a bit too loud- and he crept silently into the halls.

Footsteps made his cerulean eyes widen; and in a last moment hope, he tried to duck behind the door, which was not easy with his six-foot frame.

"Alec?" A voice hissed, and he bit his lip, hesitating before answering in a whisper, "Yeah?"

"What in the absolute hell are you doing?" His sister peeked her head from around the corner, dressed in nothing but her nightclothes.

"Nothing," started Alec, "I'm going to bed."

"Why are you dressed?" Suspicion lay in her voice, and Alec made a mental note to leave clothes for the next time.

"I'm not," He stated dumbly, and in the darkness, he saw Isabelle rolling her eyes. She took a step closer to him as he readjusted his shirt, biting on his bottom lip again.

"Where have you been?" Izzy looked up at him, one eyebrow cocked. Alec sputtered and stammered and finally answered- "Here."

She rolled her eyes again, "No you haven't. Jace was looking for you."

Looking up at her brother more, Isabelle grinned.

"You've got glitter in your hair."

His horror was clear on his face.

Alec's hand shot up and he ran his hands through his hair, looking more than mortified. "I do not," he defiantly stated, and Isabelle reached up and plucked a speck of glitter from his silky, ink black strands. She showed him, "You do."

Alec's entire face was red.

"I don't know where that came from," he insisted, mortified and horrified and embarrassed.

His sister merely looked full of joy. "Yes, you do. We both know you do," said Isabelle gleefully.

He shook his head, but Isabelle only laughed.

He could only imagine the amount of horror on his face.

He made another mental note to be more careful about these things.

"I do not have glitter in my hair."

More aggravating laughter.

"You do," Isabelle grinned, and, in uncanny timing, Alec's phone buzzed twice.

He picked it up, glanced at it and quickly shoved it back in his pocket, his face even more red.

However, it wasn't before Isabelle saw it.

'You've left something, darling. –M'

'No, I am only teasing. I just want you to come back. –M'
