The Apprentice trapped him in a book. Therefore, he did something indirectly. The Sorcerer directs and the Apprentice takes the appropriate action. I'm sure the Apprentice will show up now that the writer has done it again.

Noone knows of the Sorcerer except Rumple, the Apprentice, and Blue. Pinnochio found out somehow later.
