Hedwig is a 9-year-old boy obsessed with hip-hop — in Glass he notes that his latest obsession is Drake, even though he still has love for Nicki Minaj — who bonds with Casey (Anya Taylor-Joy) after she and two other girls are captured by the Dennis identity in Split. His lisp makes him the most easy to discern from the others, as well as his childlike behaviour (dancing on tables, as you can see in the photo above). Although he's naive and harmless (for the most part), he's able to control Kevin's body pretty much whenever he wants. That ability makes him useful to Patricia, who begins using him to exert her own control over The Horde in Glass.
