Luckily for her, Lucy had quickly found a use for the portable Hollywood-certified bouncy mat she bought the previous afternoon (they were 50% off at Wal-Mart). When the clock struck midnight, Lucy furtively placed the mat underneath Alicia's window outside the building. Then, Lucy entered Alicia's room (through the door, obviously). Flashing a smile, Lucy locked the door behind her, commented on how ugly Alicia's nightgown was, and apparated a knife from behind her back. Before Alicia could make a sound, the same knife was stuck buried deep in her chest. Lucy opened the window, leapt out and landed safely on the bouncy mat below. She then packed it up back into her room, and waited for morning to come.
She was there when Howard unlocked and opened the door. But to her horror, Lucy realized the window she escaped from was still open! Telling Howard his shoelaces were untied, Lucy used Howard's moment of pedovista to rush to the window and lock it before kneeling in front of Alicia's corpse to mask her suspicious behavior as an act of sorrow. Only Lucy knew the truth.
