The bear’s worn muzzle seemed to stare straight at him. Ethan’s blood ran cold. The image of the little bear holding his arm as he walked across a park as a child. A world of memories spun around him.

The yard sale owner, a teenager with bright pink hair, seemed to sense his focus. She leaned forward, a mischievous grin on her face. "You like him?"

Ethan just stared. His head was swimming. The details of the bear, the missing eye, the stitching coming undone on the right arm, all felt perfectly clear. It was as if time had warped.

He nodded slowly, unable to break the spell.

"Five bucks. Bargain." The teenager held out her hand. Ethan’s hand moved mechanically, reaching for his wallet.
