The information around is that it's not so much about an affair, roman and everyone else are trying to create stories that they profited somehow from the affairs.
They've been trying to use the affair to show the two of them were making money or something on the case. There's no reason to bring it up in court who paid for dinner.
From the sound of it from that meth bitch, shes trying to prove willis was paying wade with cash to hide the fees or some convoluted shit like that.
She was trying to trap wade for an hour about using her cc for cash.
Who the hell knows what shes thinking, they only had a month to make the case up.
