"Potter - a word," in the past, that sentence would have sent chills up Harry’s spine, but now, Harry was used to Snape holding him back after class every three or four weeks to check on his neck. Last time, he had sat in silence staring at Harry’s unhealed injury with a heavy frown for an entire sixty seconds before he had dismissed him. Harry expected a similar treatment today, and so sent Ron and Hermione on ahead as usual (he didn’t bother telling Draco though, knowing he would wait outside of the classroom anyway).
