In the scene narrated by Michael (Vijay Sethupathi), Michael's owner Shanmugam (Narein) contacts him through phone while Michael is in haunted house and enquires about the parcel delivery. In the scene
they share a unclear conversation. Director explains the crooky game played by Michael in the end where actually Michael acts in a way that his voice is unclear to his owner to avoid suspicions against him. Hence as per logic, in both of the scenes, the dialogues should be same. But in both of the scenes, dialogues and Michael's modulation totally varies.
