There was a clatter as the basilisk fangs cascaded out of Hermione's arms. Running at Ron, she flung them around his neck and kissed him full on the mouth. Ron threw away the fangs and broomstick he was holding and responded with such enthusiasm that he lifted Hermione off her feet.
Harry: "Is this the moment?"
When nothing happened except that Ron and Hermione gripped each other still more firmly and swayed on the spot, he raised his voice.
Harry: "Oi! There's a war going on here!"
Ron: "I know, mate. So it's now or never, isn't it?"
Harry: "Never mind that, what about the Horcrux? D'you think you could just--just hold it in, until we've got the diadem?"
He and Hermione set about gather up fangs, both pink in the face.
