"Where's the damn vanilla extract?" Alec murmured beneath his breath, shoving the rusted shopping cart in front of him as he moved down one of the many aisles of the blasted Costco, his eyes raking the shelves. His nostrils flared, his fingers clenched and unclenched into fists at his sides. He didn't think he'd ever get so aggravated over something so… somundane as grocery shopping; but it was Izzy's birthday, and his mother wanted to bake a cake, and they were out of vanilla extract. So, naturally, he'd have to search and buy the damned product himself.
He was still swearing beneath his breath when suddenly a little bottle of, lo and behold, vanilla extract floated off the shelf a little farther down the aisle at Alec's eye level. He gasped, startled, then quickly snatched the bottle out of the air. His hands were trembling only slightly as his head whipped around, looking for the warlock responsible.
"I do believe the vanilla extract is in your hand, Alec, darling," a voice said behind him, tinged with sarcasm. The young Shadowhunter whirled, fingers brushing the stele hidden inside his jacket. Upon making contact with the familiar catlike eyes, Alec relaxed, dropping his arm. He felt somewhat guilty for not recognizing the voice right away. "Thanks, Magnus."
