Brian stuck to the auto cue too much and what little ad-libs he had were either a bad pun, flirting or innuendo. I am hoping Emma gets more free reign to do her own thing and isn't too strictly keeping to the cue. As long as she keeps it flowing she can basically just have a chat to the audience in between like Davina did. She can explain the events of the house and call out the results and talk about phone lines and all that but in between that is when she can be more informal and casually talk about the house or too the audience in her own way though not emulating Davina but she can bring a bit more personality to the show.
