then told that the attacker was killed in the crash and his right hand is missing, hence the nails can't be seen for identification. Still shocked, Janet takes her son and moves to another house, collects all their belongings of the crash from the hospital, and burns it in the backyard. Martin is discharged thereafter and is brought to the new house. Janet notes that Martin is acting weirdly, and he has a long nail on his right hand. This makes her suspicious about his identity and she goes to see the dead body again in the hospital. She notes this time that the dead body is that of Martin, but then is shown that the body has decayed teeth while Martin has good teeth.

A relieved Janet goes back to the house to Martin, but is shocked to find his teeth decayed, implying that Martin is dead and the attacker was the doppelganger who took over Martin's persona. The doppelgänger attacks Janet and David like a zombie. They run to the neighbor Mr Upity for help, where Janet hides in the stable from Martin's doppelganger, but then finds David there, who is now having decayed teeth and is a doppelganger of David.
