But there's still no explanation for how it came about that the first taxi driver was shot, as no one knew what he told Marcella in the underpass except his brother, unless it is him but I don't think it was.
Again last night it was a case of the disappearing scab/wound like Jason's in past episodes on his nose.
Marcella was neck-sliced by the "brother" taxi driver and told him she moved Graces body.
Then she woke up at her house.
Then she went into work and got told off for being late and she definitely had a plaster on her neck.
Then the scene at the kids school, she was plaster and wound-free - the very same day.
So is it relevant or not, and did she actually move the body like she said she did, and if so, why?
Hopefully all will be revealed tonight but surely all the millions of loose ends can't be tied up in just one hour.
