As it was Anakin's first day in Storybrooke, he was unfamiliar with the idea that he wasn't technically supposed to exist. He wasn't familiar with the idea that he appeared as a character in a movie. He was already having a hard enough time as it was, dealing with things he had already learned. Magical portals, sons of his who were nineteen and only a few years younger than him.
There was a slight smile from Anakin when Darcy mentioned a combination of coffee and chocolate. While he wasn't familiar with the concept of coffee, he was familiar with chocolate. And he decided that anything with chocolate would be good. Well, almost anything. There were most likely a few exceptions, like with anything.
He settled into his seat, and reached for the cup of coffee. He took a tentative sip of the mocha, and then peered at it fr a moment. "...this is really good, Darcy Lewis."
