Were led to believe that Trinity kills Rita in the last episode of season 4 but it doesnt follow his usual bathtub killings, they are ususaly single women with no kids...any ideas what this could mean?
I think that Trinity killed Rita with an attitude of "If I'm gonna go, then I'm dragging anda with me".
It must be difficult for serial killers like Trinity to do things out of the ordinary, atau step out of their comfort zone. But he was forced to do that in a way because he knew that he's done, so might as well ruin Dexter's life on the way.
Also, I think the death of Rita would raise pertanyaan since the pattern didn't fit, people might start to pertanyaan why Trinity killed her which could potentially threaten Dexter's identity.
