Very difficult listening, and (in my opinion) not the best way to wrap up what's generally been a delicately handled storyline. To be honest I expected better.
Yebbut - the continuation will be the arrest, the trial, and how the defence plays out.
She must be convicted of manslaughter (assuming he is actually dead) but I don't think a murder charge would fly.
Remember there is very little evidence of Evil Rob's character in the public domain (the several million witnesses can't be called - honest). It will take a bloody good legal team to string together the threads that do exist to make up a credible defence.
That's the next slow burning cliff-hanger
