Going on the point made above, how did Draco become the master
of the wand? When he was with DD on the roof prior to DD death
in HBP, he didn't defeat DD. He used  Expelliarmus as DD got to
the roof and the wand fell down. No where in cannon dores it
mention that Draco picked it up. Are we to presume this ?

Hope someone can clear this up for me

Thanks
