The man referred to in the title is Joel Abrigore, the director working in cahoots with Sammy Jo to swindle Blake out of his money by using an impersonator for Krystle. The real Krystle bumps into him twice in this episode and is unsettled by him.
Rita has clearly had rhinoplasty to help her resemble Krystle more as can be witnessed by the fact that she is wearing bandages on her nose. However, she is also wearing sunglasses on top of that, which is not recommended until at least six weeks after such an operation.
