Ricky has a run-in with yet another previous lover of his in these spoilers for episode 21 of season 3, "Young at Heart". Check it out:
- Grace goes out with Adrian to help shop for her wedding dress, and Adrian is thinking about marrying in a church.
- Grace convinces Amy to help throw Adrian a baby shower, since Adrian threw one for her back when she was pregnant with John. Little does Amy know, Adrian's planning to also throw it in Amy's face that she had wild, crazy, good sex with Ben.
- Though it was Amy's idea in the first place, Ricky's getting impatient that Amy's putting off moving in with him. But when he rushes over to the Juergens' to discuss it with her, he runs into an ex-lover of his - Karlee - who just happens to be the sister of Ashley's new study-buddy, Toby (the two study-buddies are going out on a non-study date). Karlee invites herself to Ricky's place that night, but when she shows up, Ricky refuses to answer the door.
