If you think she didn’t care about the answers, you missed most of what’s going on. The process is similar to a trial: she knows full well what he’s trying to avoid admitting and was very carefully inching him into a situation where he had to either answer honestly or admit that his previous answers had not been correct. Each time he gave their usual spin rather than answering she recognized it as such and moved him on to something which highlighted the inconsistencies in his answers.
