Yes, I know she can be very, very annoying but we saw a different side to her last night when she was telling Bob about the girl that set herself alight in her cell.  She  obviously had affected by it and it showed she can be caring.

Its a pity that Viv's prison experience hasnt made her a better or more sympathetic person, she is still the spiteful rumour spreading old witch she always was. 

If we are to believe this storyline surely prison would have changed her instead she has just reverted to usual spiteful mode again.
