"You only say that because you can't catch me!" Jace smiles, turning to face Alec and walking backwards. "First one to the shop has to eat Izzy's cooking."

But he doesn't wait for Alec's reaction. He's already running, more like a Mundane than a Shadowhunter because they are in public and he doesn't have his stele. And maybe a little because running gives him a weird sense of deja vu boarding on panic.

Suddenly, Alec winning doesn't seem so bad and he stops, turning to find him in the crowd.
