‘Luther’ Series 5 Episode 3 Review: 8 Burning Questions We Now Have

Has Jeremy got a brain tumour?

Another visit to Jeremy’s office allowed Halliday a chance to get a closer inspection of the brain scan he was looking at when they last spoke to him.

After Halliday managed to nab a picture of the scan, a pathologist quickly confirmed that the person had an inoperable, frontal lobe tumour, leading Halliday to suggest the person whose scan Jeremy was looking at was his own.

She explained to Luther this could account for Jeremy’s deviant behaviour, and it would also explain why Vivien has been so loyal to him. Is Halliday on to something, or was the scan related to something else?

Will Jeremy strike again?

With the killer still on the loose following his wife’s arrest, police have got his face all over the news to try and catch him. However, in the trailer for the final instalment, we saw Jeremy turning up at the house of the his second victim’s school teacher from episode one. Will she be murdered next? Or…

Does the school teacher know Jeremy?

When she was seen opening the door to Jeremy, who was holding a bunch of flowers in the preview, she greeted him with a smile, suggesting she somehow knows him. Is she in on his crimes? Or perhaps she is a friend unaware of his murderous activities? Either way, we reckon there’s more to this relationship.
