“I really want to dunk you right now,” I say. “But I'm afraid I’ll hurt you.” His mouth pulls into a disbelieving smirk. “As if you could hurt me, Little Sharpie.” The nickname is like a bucket of ice water over my head. He never calls me that. Ash, Declan, Leo, and some of the other guys have been using that endearment for me since I was eighteen, but Jack never has. I can’t explain why it hurts.
