Kelly's facial reaction indicated to me she recognized Renard. If she thought he was an "unimportant visitor" then she still would of informed Nick of this mysterious man who left Catherine's house since it could be "important" to saving Juliette's life. Since she failed to inform him, this tells me that she now knew who was behind this conspiracy and thus tricked Nick into believing she is leaving instead of stealing a car to possibly confront Renard. I still have a problem fulliy trusting Kelly and who knows, since she has the coins she may go and deliver them to Renard. Kelly may have not known there was a prince in Portland until she saw Renard then of course she wouldn't admit knowing who it was to Catherine anyway, whether she is secretly working with Renard or not and Catherirne was not going to tell her the identity of thei "Prince" in order to protect Renard.
