I believe the conversation goes:
R: What are you hoping to achieve?
H: (miffed) Ask them...
R: Is that why it’s important for you to come and talk to them?
H: (pissed off now) Rhiannon, don’t behave like this!
I suppose some posters are correct in that it’s a small snippet of what may have come before but he really does himself no favours speaking to people in that manner. It did look very hot there though, I don’t do well in the heat myself...
