Karen says that Sid is blind to Abby, but he defends her and they argue. Jeff files for custody of the kids. He and Abby talk, and he admits he wants her back. Abby sleeps with him so he'll drop the case, and then tells him that it was a one-time thing. Jeff is angry and says she's not playing 'fair' with him. One of Laura's clients kisses her, but she says she can't cheat on Richard. Abby tells Richard that it's over between them.

Ginger's sister Cindy visits, and gives Eric marijuana to hold for her. Sid finds it and is very upset. At a party, Cindy freaks out and runs into the ocean. Eric saves her, but she's in a coma. The doctor says the pot had angel dust in it. Eric is upset as everyone blames him, thinking it's his pot. Cindy finally wakes up, and tells everyone that it wasn't Eric's pot.

J.R. comes to town (again). He wants to form a corporation with Sid and patent the engine that Sid invented. Sid refuses. Abby steals the engine plans and gives them to J.R., and has him sign a contract to protect her interests. They sleep together. Karen tells Sid that Abby stole the plans, but he doesn't believe her. Karen and Val are suspicious when Jeff comes to pick up the kids, and packs all of their things into his van. Karen goes to J.R.'s hotel to tell Abby she thinks Jeff kidnapped the kids, but Abby doesn't believe her and says Jeff is just trying to scare her again.

Jeff doesn't return the kids and Abby's really worried. The FBI question Gary about Frank and Roy, and Gary finally admits his illegal dealings to Sid.
