After Aunt Sharon suddenly left on a business trip, Riley was welcomed by Mickey Smith, Fiona Fortuna, and Agora Tchotchke. The next day, she invited Mickey over, not knowing he would bring Agora with him. Riley tried to flirt with Mickey, and Agora got angry with her. She stormed off in a huff, leaving Mickey at Riley's house. Mickey called Riley the next day and asked her if she wanted to go to the Starlight Cafe and Market, where they shared their first kiss, and became boyfriend and girlfriend. Later, Fiona called Riley saying that her ex-boyfriend from high school, Dylan Kincaid, moved into Four Corners a few weeks before she did. He called Riley, and invited himself over to her house for dinner. They fell in love again, and Riley was conflicted about her feelings for Dylan and her relationship with Mickey. Riley invited Mickey to the gym, not knowing they would meet Dylan there. Mickey thought Riley was dating Dylan, and dumped her on the spot.
Dylan later went to Riley's house to comfort her. Feeling particularly down, Riley decided to go to the boutique. She invited Dylan, but he made the excuse that he had to work. So she then went alone, and saw Dylan there on a date with Ashley Sinclair. After attacking him, he dumped her, and Riley discovered Dylan dropped his wallet during the fight. She took the money, and spent it on clothes, but went home when she saw Mickey with Agora, since the two of them were engaged now. Riley then decided to make up with Mickey, but when they finally do, he had to go and marry Agora.
Riley was devastated, and things only got worse when Dylan showed up yelling at her for wrecking everything. Aunt Sharon showed up with the police, and Dylan was arrested for kidnapping Sharon and holding her hostage in his basement. Riley found out Agora was involved too, and went to Old Grove Gardens to stop the wedding between Mickey and Agora. When she got there, she told Mickey everything, and Mickey left Agora at the altar.
Agora was furious with Riley, and got in a fight with her. Riley won, and Agora was arrested. Mickey asked Riley to marry her on the spot, and they went on their honeymoon to the Simaican Isles, a play on the Jamaican Isles. When they got back, Sharon announced to them that she was giving them the house, and left on a date with a guy she met over the internet. Riley then became pregnant, and she and Mickey threw a house party to commemorate the occasion. Riley then has the baby(s), and this is where the storyline ends.
Riley, Mickey, and their baby(s) are in the end available in the neighborhood view as a playable family.
