What happens with Draco and Voldemort in the movie?

I had the same feeling but I don't see Voldemort being the hugging type. Besides, he doesn't really hug Draco - who is very reluctant, almost disgusted, to be so close to the Dark Lord. I had rather the feeling he was telling him something while aiming his wand toward ... ? I don't know, but not a very friendly hug if ever. OK, who ever said that Voldemort was a friendly guy ?

Yes, he did. After Harry supposedly died and Voldemort announced that it was time for people to either join the Death Eaters, or die. At this moment Lucius and Narcissa tell Draco to join them. Draco does, as in walks to Voldemort who then kinda hugs Draco telling him 'well done' or something.
