who is killing her in happy death day
Happy Death Day Tree wakes up in another loop. Confused and angry that the time loop continued after she killed Tombs, Tree returns to her room where Lori offers the cupcake again. Tree realizes this was the only time she had ever eaten the cupcake and died in her sleep. Tree deduces that Lori is the true killer; Lori had poisoned the cupcake, but when Tree declined to eat it, she utilized her job as a nurse in the hospital to drug and frame Tombs for Tree's murder. Tree tries to coerce Lori to have a bite, however when Lori refuses, Tree decides to take the cupcake to the police. Lori lunges at Tree, locks the door and confesses that she was jealous of Tree's affair with Butler, before engaging in a fight. Tree manages to stuff the cupcake in Lori's mouth before kicking her out of a window, sending her falling to her death.
