Mrs. Lovett: Nothing's gonna harm you... not while I'm around..(Whispery singing)
Mr. Todd: What is that?
Mrs. Lovett looks at the small black stick on her left hand.
Mrs. Lovett: Its my wand...
Mr. Todd:............ your wand.
Mrs. Lovett: Yes... my wand..... Oh, for heavens' sake, Mr. T
lets just kill that boy?
Mr. Todd:What is it so special about this boy?
Mrs. Lovett: He's the boy who lived.
Mr. Todd: Not in my parlor. (walks out from the darkness and sliced Potter's throat)
Mrs. Lovett: Maybe I'll call it Potter Pie.
So yeah, Harry Potter goes to investigate Snape's last whereabouts and he too fell in Todd's hands. HA HA HA
