Tennison's glasses suddenly appear on her face during the second interview with Milan Lukic.
Tennison refers to Zigic as a Bosnian to the SWAT team leader, but earlier his nationality is represented as Serbian.
Towards the beginning Tennison says she is 54 years old, however in Prime Suspect 5 she says she is 50. As Prime Suspect 6 is set 7 years later she would be 57 not 54.
