Difficult to be objective without being in the courtroom but - I thought she did indeed hold her own.
I felt the KC over did it by spending too much time trying to make her out to be an habitual liar. She admitted that she had told an initial lie, due to fear, but overall, the remainder of her evidence sounded honest.
I also thought her comment - this trial should be all about Olivia - will have gone down well with the Jury, who may have become weary listening to the KC keep pushing away about the relationship ( or lack of ) with TC.
Also, the fact that the Judge had to remind the KC that the witness had already answered him, when he kept pushing a question, did him no favours.
Hopefully the Jury can sift the facts from the witness baiting.
And I imagine TC is cringing as he listens to the description of his sexual capabilities.
