They first met when Naomi wanted to buy a house near CU.
The romantic relationship between Naomi Clark and Austin Tallridge began in Season 4, Episode 7, It's The Great Masquerade. In this episode Naomi left a "confidential" video-message for Austin(the message was made public by Holly). In the video she said that she likes him but she doesn't want her heart to be broken. The relationship lasts until Season 4, Episode 12, O' Holly Night in which Austin is upset with Naomi as she has changed him into a submissive boyfriend. Naomi catches Holly and Austin about to have sex and that marks the end of their relationship.
