In Harry Potter and the Prisoner of Azkaban (2004) movie, Hagrid is pelting stones on the surface of the river, and says about Malfoy:
Hagrid: He said Buckbeak was a deadly and dangerous creature...who would kill you as soon as look at you.
Hermoine: And then?
Hagrid: And then he asked for the worst, did old Lucius.
What does "did" refer to?
