[ruination]

I am totally confused.

How can the wise general public not see that Darnell is one of the best people ever?

If I can begin to tease out your problems with him ...

he was only mean and horrible to Sara cos he fancies the knickers off her, and she totally dissed him in that department ... she was only flirting meaninglessly with him, and he let his guard down ...

of course he turned against her, in self-defence.
