Loose Ends in 'Sveket' (Betrayal) [Spoilers!]
Since this request for help is directed to those who've already watched this episode, I think it's best to shield what follows with the "spoiler" feature:
I just saw the "Sveket" (Betrayal) episode, and I came away confused or perplexed about a few crucial plot points.
Here's what I think I know:
By the end, we understand that the stocky ponytailed geek, Tore, put surveillance cameras in the Wredin home which were supposed to be connected to Julia Wredin's home computer; the camera recorded Julia Wredin's murder.
However, Tore also has an app that lets him remotely tap into the surveillance cameras. When he views the remote video, he sees Julia's murder-- although it's not clear (to me) if the video reveals the murderer.
I assume it does not, because Tore and his girlfriend Alexia use the video to blackmail Erik Wredin, and treat him as if he were the murderer.
Eventually we learn that Amanda was the "betrayed" person who murdered her mother. But unless I missed something, after the murder Amanda left the house, leaving her mother's body where she fell.
So, am I right to think that Tore returned to the house, wrapped Julia's body in plastic and dragged it out to the underbrush, then cleaned up the crime scene?
They make a point of telling us that Tore tried to remove all the signs of his presence at the home, but why would he need or bother to move the body-- or clean up the blood, for that matter?
I can see taking the murder weapon (bloody knife), but "disappearing" the body doesn't seem crucial to the blackmail, unless it was done to throw off the police.
Also, it seems improbable that Tore would risk returning and taking time to clean up the place, since he couldn't be sure that someone (Erik or Amanda) would show up and catch him in the act.
And although we're told that the police couldn't find Julia's computer, which Tore took to cover his tracks, are we to believe that the highly-competent Nyberg didn't find any traces of the surveillance cameras-- which Tore presumably had to remove during his extensive post-murder cleanup?
I guess part of my puzzlement arises because I find both Tore and Amanda's characters inconsistent.
OK, Amanda is a deeply troubled young woman with "issues", but to me even her tormented, irrational behavior doesn't seem plausible.
Although Tore is clearly meant to be a cunning, clever geek, he also seems to be making up his plans as he goes along-- with help and instigation from the more deranged Alexia. After all, he only "lucked out" in the first place by catching the murder on video.
For me, it's a stretch that Tore could sort of blunder along step-by-step with the blackmail scheme, yet do such a good job of covering his tracks until the end.
Finally, another minor puzzle: what was the business of Erik cutting his hand on the booby-trapped car door all about? The injury looked pretty serious, yet after one follow-up scene where Amanda asks about the injury, it seems to disappear completely.
Sorry, maybe it's me. Or maybe the writers are seeding the final series with these points of confusion so viewers will experience the same mounting confusion from which poor Wallander now suffers.
