Alec woke slowly, light shining in his eyes. "Magnus?" he said as he sat up and rubbed his eyes. As he lowered his hands and looked around he realized he was on the couch in the Institute, not in Magnus' big, fluffy bed. Which was odd. He distinctly remembered falling asleep the night before with Magnus' thin arms wrapped around his waist… and his warm breath on the back of his neck… their legs tangled together…
Alec shook the images out of his head before he had a – ahem- problem to deal with.
He stood up and looked around. The Institute looked especially deserted today. He cupped his hands around his mouth. "Jace! Izzy! Anybody home?" he yelled. When no one answered he sighed and started fishing around in his pockets for his cell phone to call Magnus.
He froze as he heard footsteps thumping down the stairs. As he turned to identify whoever it was, he was unnerved to see Jace dressed in a white suit with white Halloween bunny ears sitting on his head, looking worried.
"Jace?" he said. "What's wrong?" But Jace completely ignored Alec and, without looking at him, pulled out a silver pocket watch.
"I'm late!" he exclaimed before sprinting out the Institute's door.
"Jace? Jace, come back!" Alec yelled, following after him. "Jace, what are you late for?"
Jace continued to ignore Alec and kept running, still yelling "I'm late!"
As Alec followed after him he took an abrupt right turn and disappeared. "Jace!" Alec yelled at the empty air where Jace used to be as he started to skid to a halt. "Where did y- Ahhh!" He cut himself off because just as he came to a complete stop, the ground opened up beneath his feet and swallowed him whole.
