Or as has been pointed out elsewhere, i think - for Carla to have finished Tina off.
With Rob being left thinking he'd done it.
Now, that would have been more interesting.
What was interesting though in those closing few minutes was the realisation that Rob's actions have unwittingly and unfortunately made Carla look guilty - which wouldn't have been his intention, obviously. Also the realisation that everyone knew about Peter and Tina (albeit by that point) because Peter had just confessed. All of that threw him.
So could still be interesting, whatever - given the whole Carla / Rob / Peter history - like with all the previous factory stuff between them all.
